Sleep Apnoea and Sleepy Driving
We discussed Sleep Apnoea in drivers before when we dug up some frightening statistics regarding the prevalence of sleep disorders amongst drivers in Britain. As this is such an important topic and often asked about in the various forums, we decided to dedicate another post to the matter of Sleep Apnoea and driving cars or trucks.
There are many good sources on the web benefiting drivers with sleep disorders. A good starting point is the road safety charity aptly named Brake. They list a staggering amount of scary statistics, pointing out the large groups of people endangering our roads on a day to day basis. They estimate that one in ten road accidents are down to driver sleepiness; that statistic alone warrants utmost caution among those who know they aren't sleeping well. Brake quotes:
Sleep scientist Melanie Marshall says, “Untreated, undiagnosed sleep apnoea individuals are more lethal on our roads than individuals who have been drink driving.”
Brake has great further information on Driver Tiredness, Driver Stress & Emotions, Risks for Older Drivers and Laws regarding Death by Dangerous Driving. They also have PDF documents for fleet managers containing information about how they can assist their drivers in road safety. Those relevant to sleep disorders include Stress & Distractions and Driver Assessment & Monitoring.
If you are unsure whether you are just not sleeping well temporarily or a sleep disorder might cause your sleepiness symptoms, take this free online screening test and discuss the results with your doctor. If a clinical diagnosis confirms you have a sleep disorder like Obstructive Sleep Apnoea (OSA) you are obliged to inform the DVLA.
Group 1 licence holders (car/ motorcycle) diagnosed with sleep apnoea must stop driving until the symptoms have been controlled and confirmed by medical opinion.
Group 2 licence holders (LGV) diagnosed with sleep apnoea must stop driving until the symptoms have been controlled, and must have ongoing treatment. Licensing reviews will be carried out regularly, usually annually.
The Driver & Vehicle Licensing Agency (DVLA) has many pages on their website dedicated to tired driving and Sleep Apnoea in drivers. This PDF leaflet called "Think! Tiredness can kill!" explains the implications of Sleep Apnoea for drivers. Their D9 form tells us:
If you have ever had or presently suffer from any of the following
conditions you must write to the Drivers Medical Group, DVLA,
Swansea SA99 1TU or telephone on 0870 600 0301 with the nature
of your condition, as it may affect your fitness to drive.
FAILURE TO DO SO IS A CRIMINAL OFFENCE PUNISHABLE
BY A FINE OF UP TO £1,000.
- Narcolepsy or sleep apnoea syndrome
The DVLA's medical section has all the information you need including how tell them about your sleep disorder and what happens next. Your licence can be accordingly issued, revoked or refused. In some cases they may contact your doctor, arrange to be examined or ask you to undergo a driving assessment or test. They aim to resolve most medical enquiries within 15 working days. CPAP users tend to get their licence re-issued after they confirm with the patient's doctor that the CPAP therapy is having the desired effect.
Some people may feel opposed to risking their licence by telling the DVLA or even by seeing their doctor. After all, some rely on driving to pay their bills and food. It is important to realize the full extent of the risks you expose yourself and other road users to if you keep on driving whilst sleepy, fatigued or lethargic. It's not just yourself who can be harmed or killed. Think about your children in the back seat or the car behind you.
UPDATE: There is a scheme called "Access to Work" run by the Employment Service (ES) which can help people with disabilities and those who's licence has been revoked for medical reasons to regain access to work. A good write-up can be found here and an evaluation here.
Some of the slogans designed to make you take direct action:
- [Disabled Parking Sign] Every Hour A Driver With OSA Makes Someone Else Eligible To Park Here
- Daddy Used To Drive A Big Lorry, Then He Fell Asleep
- Bet You Wish You'd Crashed At A Mate's
- You Drive For A Living But You'd Kill For Some Sleep?
- Think You Can Do The Job With Your Eyes Closed?
If you are worried about nodding off whilst at the wheel, we urge you to do the following:
- Take this online test today.
- Consult your doctor and if need be, get referred to a Sleep Clinic to get diagnosed.
- Based on the outcome of the sleep lab test, consider your sleep disorder treatment options. This can range from surgery or dental splints to CPAP or lifestyle changes and weight loss.
- Don't forget to tell the DVLA about your test results.
- For some forms of treatment you may have to join the queue on the NHS waiting lists though most are available privately as well.
- Once receiving treatment, arrange a follow-up with your doctor or sleep clinic to confirm the symptoms have sufficiently reduced.
- Now re-apply for your drivers license, if applicable.
- Don't drive when feeling tired!
