Truck Drivers South Africa

In South Africa the Road Traffic Data Indicates 
In January 2006 more than 244 000 trucks were moving freight across the country.
In January alone 1 875 trucks were sold – an indication that road freight transport is growing with enormous speed.
There is a high rate of accidents and one of the factors that have been identified as contributing to this problem is fatigue, and this includes truckers, especially with the distances they have to travel transporting goods.
There is a need for convenient, safe and comfortable truck stops on all major road freight routes around South Africa

Research on Drowsiness / Driver Tiredness amongst Truck Drivers

Driver tiredness poses a significant risk to road safety and several studies have indicated that this problem is experienced daily by Truck drivers

  South African Research:
In South Africa a research study has been conducted by Nelisiwe Magubane & Mala Ramanna from the Interdisciplinary Accident Research Centre of KwaZulu –Natal on the topic “Truck Drivers and Road Crashes in South Africa
This study concluded amongst other findings:
Main problems experienced by truck drivers:  39% Fatigue relate, Main causes of road crashes: 41% fatigue related .

 A study in the SA more than 36 percent of truck drivers said that finding a rest area in which to park is a problem every night.

More than 80 percent said that at least once a week, they continue to drive past the point of feeling "safe and alert" because they cannot find a place to stop and rest.
Factors which discouraged Truck Drivers from parking in public rest areas in New York included inadequate parking, enforcement of the two-hour parking limit, prostitution, lack of security, and poor or expensive food.

In a 1997 survey of 593 long-distance truck drivers randomly selected at private truck stops and public rest areas in New York, 25 percent of the drivers said that at least once during the last year, they had fallen asleep while driving - and 17 percent said it occurred on more than one occasion.

The recommendations from this research include the following:
There should be government legislation that forces drivers to stop between 11pm and 5am for compulsory rest.
Most drivers sleep for +-4hrs per 24hr.

Companies should allow drivers more family time. This will stop the use of prostitutes but also de-stress drivers.
More safe and clean truck stops are needed.

Alternatively, along the route there should be lay-bys constructed with stadium lights and security so that drivers can sleep in relative safety. This is especially so on the N3 because drivers regard this national highway as dangerous.

Trucks should be fitted with communication devices, e.g. two-way radios. This can act as a mechanism to warn other drivers of possible hijacking situations or as a tool to ensure the safety of the truck and driver.

Almost all truck drivers are interested in participating in any government road safety strategy that will improve and promote their skill.

Drivers need to attend regular driver training courses to improve their skill as well as stop complacency. Further, there should be relevant training courses for truck drivers that carry specialized/ dangerous goods e.g. chemicals.

  Transport Authorities, Truck Stops and
Road Safety

At the opening of Engen Highway Junction on the 28th of May 1999, the Minister of Transport, Mac Maharaj, emphasized that the road freight sector and its associated stakeholders were the first business sectors in South Africa to forge ahead in a partnership with government, employers, unions and NGOs on board to tackle the crisis of road safety in the road freight industry.
In 2005 the Department of Transport launched the National Freight Logistics Strategy.This Strategy addresses issues of “reducing the cost of logistics to the economy" and ensures "that social and economic objectives are met within the freight logistics systems".

The commitment to the National Freight Logistics Strategy was further strengthened with the official opening of the Ventersburg Truck Stop by Minister of Transport, Jeff Radebe on the 3rd of March 2006. 

Government, via the Department of Transport (DoT) and the South African National Roads Agency Ltd (SANRAL) have initiated a programme whereby new truck stops are being built to improve truck transport efficiencies and driver job satisfaction, while simultaneously empowering local communities.

Nazir Ali, CEO of the South African National Road Agency reiterated that these Truck Stops represent a coming together of different departments of government to promote road safety and trucker rights.

Advantages/ Characteristics of modern Truck Stops
The best way to address driver fatigue/ driver tiredness by offering a good sleep
Security systems with cameras and lighting can prevent the threats of hijacking, theft etc.

Increased sanitation with spotlessly clean ablution and shower facilities
High quality food

An excellent venue to address HIV education
An opportunity to boost the local economy with a continuous stream of travellers passing through

Additional income for local business providing truckers with various necessary services including food and drink, groceries as well as truck repair and parts provision.

A Medical facility and medical care provide an opportunity for truck drivers to check HIV/AIDS and diabetes status and have their eyes tested."
These facilities may have phones so truckers can safely call families and conduct other business during their meal breaks Modern Truck Stops have high speed wireless internet access and an internet kiosk ,It is envisaged that Trucks Stops will make a significant contribution towards road safety in South Africa.


Why is Tiredness a road safety problem?
We live in a 24-hour society – television, international travel, the internet and telesales mean that we work and play throughout the day and night.
The fast moving pace of the modern world also means we are doing more than ever before and are constantly on the go, trying to cram as much as possible into our days. As a result of our hectic 24-hour lifestyles, many of us don’t allocate enough time for sleep and regularly find ourselves in a state of sleep deprivation.

Another reason society suffers from sleep loss is our poor attitude towards sleep. Most of us don’t take sleep seriously, as reflected in a recent survey (by Gallup) which showed that 94% of adults did not consider getting enough sleep to be important.
Many people, particularly men, also consider tiredness to be a weakness and will push on and try to overcome feelings of tiredness rather than admit that they should take a break and get some rest. All too often the prevailing attitude is that sleep is for the weak or the lazy, and that if you are strong or a hard worker you learn to get along without it.

We cannot live without sleep

Like food and water, sleep is a biological need that we must fulfil in order to survive and if this need for sleep is not met, we experience tiredness. However, the need for sleep is different to that for food and water because, while you can choose whether to eat or drink, tiredness is unstoppable and whether or not you want to you will eventually fall asleep.

Most of us need 7-8 hours/day

The majority of adults need between 7 to 8 hours of sleep per night in order to operate at their optimum. While many people “get by” on less sleep, they are probably not performing/feeling their best.

Critical skills are affected by tiredness

Many people consider tiredness to be a symptom of laziness and as something that can be overcome with will power or motivation. Unfortunately, this is not the case and tiredness and its effects are inevitable.

Tiredness has many neurobehavioral effects and it impairs our performance of all types of work - physical and mental. For example, when we are sleep deprived memory and recall of recent events is reduced, reaction time is decreased, driving is more erratic and we are more vulnerable to making mistakes.

Tiredness affects a range of cognitive abilities. In normal circumstances we can cope with these effects without too much danger. But if we are involved in safety critical work, including driving, or are involved in an emergency situation, these effects can result in major problems.

Well learned automatic responses are not vulnerable, but the following are:

Understanding a complex situation and ignoring irrelevant information.
Assessing risks and anticipating the range of consequences.
Dealing with surprise and the unexpected
Keeping track of changing events.
Developing and updating strategies
Effective communication.
Ability to think laterally and innovatively.

Driver Tiredness kills
Over the past 10 years a great deal of research has been undertaken on drivers falling asleep at the wheel and the countermeasures that can be put in place to tackle the problem. The Loughborough Sleep Research Centre in the UK has analysed thousands of motorway accidents and have demonstrated the true extent of the problem in Europe:

 Driver tiredness causes more than 20% of motorway accidents

Many of us aren’t aware just how common tiredness-related accidents are. Did you know that tired drivers are responsible for at least 1 in 5 deaths on UK motorways (1 in 10 of all road deaths)? Across Europe that amounts to about 4000 fatalities a year. In Africa the problem is thought to be even more pronounced: anecdotal evidence suggests that as many as 60% of truck accidents may be due to driver tiredness.

 Tiredness-related accidents are worse

One reason that driver tiredness is responsible for such a high proportion of fatal road accidents is because there is no braking or steering adjustment prior to these accidents

A driver asleep at the wheel will not act to avoid an accident and consequently is much more likely to cause death or serious injury. In fact, tiredness-related accidents are 3 times more likely to result in serious injury or death compared to other types of road accidents.

Tiredness-related accidents are known to be a particular problem for truck drivers. Driver tiredness is the most likely cause of accidental death of a truck driver and is the most likely reason for a total write-off of a truck.


 Causes of driver tiredness

The primary reason for driver tiredness is sleep loss. There are many reasons why sleep loss occurs, ranging from long work hours, long commuting times and family/social commitments to illness or noisy neighbours.


  Sleep loss accumulates 

A small amount of sleep loss on one night is not necessarily a problem, but what most of us don’t appreciate is that if you don’t get enough sleep for two or more nights in a row, then the effects build up.  For example, if you go for 5 days getting 2 hours less sleep than you need, you will be 10 hours “in debt” (like a bank balance) and not safe to drive.

  Recovery takes 2 good nights of sleep

The good news is that we do not need to make up lost sleep hour-for-hour and full recovery from even severe sleep loss takes only two consecutive nights of uninterrupted sleep.

 The body clock and circadian rhythms

Tiredness not only occurs when we have had insufficient sleep, but is also prominent at particular times of the day. This is because alertness varies naturally across 24 hours in what is known as a circadian rhythm. Alertness is lowest during the night (particularly in the early morning between 2-6am) and increases during the day (although there is another dip or decrease in alertness after lunch) and this cycle repeats itself every 24 hours.

The activity of all of our body systems, for example heart rate and body temperature, vary in a circadian rhythm and the purpose of these rhythms is to prepare us for sleep at night and activity during the day. For example heart rate and temperature are naturally low during the night in order to promote sleep and then increase during the day to prepare us for activity.

Circadian rhythms are generated in the brain by a cluster of cells known as the body clock.

  Early morning – time of the circadian minimum in alertness

Our circadian rhythm in alertness is the reason why we perform worst in the early hours of the morning and why tiredness-related vehicle accidents and industrial accidents are likely at this time. Anyone who has tried to stay awake all night knows that it is most difficult between 2-6am and then things seem to get easier.  You feel better as the morning progresses because your body clock starts to swing back into daytime/ awake mode.

   Siesta time – time of the circadian dip in alertness

After lunch between 3-5pm there a circadian dip in alertness that is sometimes known as the “afternoon slump”.  Again, there is an increase in tiredness-related accidents at this time of day.

Myths Fresh air and loud music will not keep you awake
Unfortunately, many of the things that we think will help deal with driver tiredness are actually ineffective. Research at the Loughborough Sleep Research Centre has shown that winding down the window, switching on the air conditioner, chewing gum and getting out to stretch your legs have a limited effect.

These strategies will improve your alertness briefly, but within minutes you return to the same level of tiredness. These strategies should not be relied on to keep you awake.

While getting out and stretching your legs will relieve the fatigue associated with concentrating on the road or holding the steering wheel, it will not remedy tiredness. If you are tired the only safe solution is to stop driving.

   Determination won’t stop you from falling asleep

Many people believe that motivation, training, professionalism, and experience can protect them, and their driving skills, from the effects of tiredness. Unfortunately, none of these factors can prevent you from falling asleep when tired.

  Microsleeps are uncontrollable and inevitable
Sleep is a basic need like food and water. Whether you want to or not, if you stay awake long enough you will fall asleep. You won’t fall immediately into a long sleep, but your body will take microsleeps that last from a few seconds to 30 seconds. Microsleeps are uncontrollable and the longer you are awake the more frequently they occur.

    When tired you over-estimate your alertness

It is important to appreciate that when we are tired we tend to over-estimate our alertness. Research has shown that many of the drivers involved in tiredness-related accidents did not recognise they were in need of sleep, and believed they were well-rested when they were not.
     Effective countermeasures

t is a driver’s legal responsibility to ensure that he or she is fit to drive and has had sufficient sleep before commencing work. There are a number of common sense lifestyle adjustments that you can make to improve sleep and general well being.


 Eat a balanced diet

Driving for a living can make it difficult to access healthy food. Drivers are typically at work or asleep when shops are open. As a consequence, drivers tend to eat high sugar and high fat meals from road houses or vending machines. Night drivers may also face additional dietary problems because they eat at night when food is digested less efficiently.

The poor diet and sedentary lifestyle of many drivers means that this group has a high incidence of obesity and gastrointestinal complaints such as stomach ulcers. To avoid these problems drivers need to ensure that they have eaten a healthy meal before beginning a shift and that they have access to a healthy meal during their shift.

Drivers should particularly avoid food and drinks high in sugar, such as chocolate, as these give you a temporary sugar-rush and then leave you feeling sluggish.  A more sustained and healthier source of energy can be found in complex carbohydrates such as bread or cereals.

Don’t go to bed too full or too hungry

Indigestion and hunger pains are obviously not going to help you sleep.

Avoid caffeine/ alcohol before bed

While you might be able to fall asleep soon after caffeine or alcohol, both of these substances will alter the structure of your sleep. Research has shown that even one glass of wine or cup of coffee with dinner influences the quality of your sleep.

 To relax, have a warm/bath or shower before bed

Many people who have difficulty getting to sleep simply don’t take the time to relax or wind down before they climb into bed. A warm bath or shower will not only help you get in the mood for sleep, but research has shown that we fall asleep more quickly if we warm up cold hands and feet. Listening to quiet music or some gentle stretching will help to relax both the mind and body and promote sleep.

Exercise regularly, but not just before bedtime

Most of us are aware of the benefits of exercise, but did you know that exercise can improve your sleep? It is important that you don’t exercise just before sleep though as the adrenalin released during exercise can make it difficult to get to sleep.

Your bedroom has an important influence on your sleep quality and should ideally be dark, quiet, cool and comfortable. You should use your bedroom only for sleep and keep computers or TVs in another room. This way you will come to naturally associate the room with sleep and feel relaxed when you enter.


 On the road

As driving is a safety critical task it is essential that you manage your tiredness on a long term basis by ensuring that you get regular good quality sleep. You also need to plan your journeys to include regular breaks at least every 2 hours.

Even with the best preparation possible, there will be times when you might have problems maintaining alertness behind the wheel. In these situations the best short-term advice is:

1. If you are feeling tired STOP DRIVING.

2. Park somewhere safe.
 Don’t park on the hard shoulder. If you’re on the motorway, take the next exit and find somewhere safe to park, or stop at the next motorway service area.

3. If necessary call someone to let them know you may be late
4. Have a couple of cups of strong coffee
5. Followed by a 15-20 minute nap

Caffeine takes about 20 minutes to take effect, so use this “window of opportunity” to have a short nap of no more than 15-20 minutes. If you sleep for much longer than 20 minutes you can fall into a deep sleep and wake up feeling groggy (this feeling is known as sleep inertia). Please make sure you lock the doors before settling down for your nap.

It is essential to remember that this advice only offers short-term relief from driver tiredness. It is an emergency countermeasure to driver tiredness and is no replacement for a good night’s sleep.
