Accidents on our roads in
Not taking away the good side of the programme, I could not stop wondering why we have taken this long to do this. Also is this going to be replicated every where in the country or only in
Driving to most city people is an every day activity whether as work or in-order to go to work or business. For those who do it as work, the sort of assessment that needs to be made to determine fitness is therefore similar to that required when determining fitness for work in other spheres of life, fitness to travel or the scope for a return to the full activities of daily living after a major illness, rather than the normal clinical priority of diagnosing an illness in order to treat it correctly. I am therefore not against taking drivers for psychiatry assessment when found to have fallen foul of traffic rules but we need to know what we want to get out of the assessment and this appears like treating an illness rather than preventing it. Questions will arise as to what we are going to do with the result of the assessment and who will pay for it. That is why the Nigerian Breweries initiative needs to be embraced. We need to have a change in our mindset about how things should be done.
It is true that diagnosed mental ill-health, may lead to patterns of behaviour such as impulsiveness, indecisiveness, excessive anger, loss of or excessive risk aversion and changed levels of arousal, all of which can increase the risks of driving. All are also frequent among drivers without defined psychiatric health problems.
Safe driving requires the driver to have effective and reliable control of the vehicle, the capacity to respond to the road, traffic and other external clues knowledge of and a willingness to follow the ‘rules of the road’. Drivers consciously learn all these skills to pass the driving test and I believe some of the people who drive in
Sound advice on fitness to drive is therefore derived from an assessment of the driver’s risk of crashing because of any health-related impairments that are likely to reduce their ability to drive safely now and in the future. In the
The questions to ask in 1 How can drivers drive safely when they do not go for driving tests to gain their drivers’ license? I may be wrong but many Nigerians have gotten their licenses without a driving test. 2. How can there be safe driving when the vehicles are not road worthy? We all know that most vehicles do not have any documented service history to show. 3. How can drivers drive safely when there are no road signs? Even where the signs are available they are difficult to read or not obeyed. 4. Why will there be safe driving when no one can be held liable for an accident? There are no insurance covers for most vehicles. Even when such covers are available, they are provided by road side third party insurance companies that can not be traced in cases of liability payments. 5. How many Nigerians drivers have been held liable for drink driving? Drinking and driving is the in thing. This can be witnessed over weekends when drivers are heavily drunk and are behind their steering wheels. How many driving licenses have been seized or suspended for drink driving?
Coming back to health, any condition that impairs perception, cognition (including alertness, attitude to risk, recall) or movement function has the potential to interfere with and impair driving and make it less safe. The road surface and its contours will have a big effect on car control. The driver needs to perceive changing conditions in order to respond to them appropriately. Non-visual clues such as noise, bumps and inertial effects can be important. Dark and unlit roads will pose problems if the driver has impaired visual contrast or dark adaptation is impaired. Congested roads pose very different problems from empty ones. Drivers need to anticipate the behaviour of their fellow road users. Precise car control is more important. Interactions with other vehicles and their drivers are the predominant skills required.
Therefore, though driver variables are the major determinant of the risk of a crash, even in the absence of any specific health-related impairment, arousal and factors that affect it, such as fatigue, alcohol and certain drugs (whether prescribed, over the-counter or non-therapeutic) all influence a driver’s performance. So, one can say that health-related impairments are only one contributor to reduced driving performance and are only responsible for a fraction of the total risk. The nature of the driving task and the features of any impairing health condition influence the way in which the risks of conditions need to be assessed, and the advice to be given.
Therefore, I would say that though the FRSC has started a good work, they need to ensure that systems are in place especially with regards to driver assessment. There should be a proactive way of preventing these drivers from getting on the road. Apart from the efforts from the producers of alcohol as exemplified by Nigerian Breweries, it may be useful to breathalyse drivers at major motor parks, have drivers undergoing appropriate testing before being issued a drivers license and ensuring that all cars on the road are appropriately insured. There should be a central databank to which a Road Safety Officer can telephone and get information on a vehicle giving the vehicle registration or insurance number or road worthiness certificate. Finally the people working to ensure drivers are doing the right thing should be adequately remunerated in order for them not to fall victim of bribery.
