One Beer, Cough Syrup and an Expired Insurance Certificate

It is 22:50 on a Friday. You have had one 330 ml bottle of beer at 5% ABV at 20:15. Because of a heavy cold you took 10 ml of cough syrup containing codeine and chlorphenamine at 21:00. You feel sleepy and your mouth is dry. You are 3 km from home on a well-lit urban road. Your driving licence expires at midnight tonight; your insurance certificate expired three days ago, although a renewal email is on your phone. A police checkpoint is visible 150 m ahead with officers stopping cars. You are alone; no passenger can drive. A taxi rank is 300 m behind you. The legal blood alcohol concentration limit is 0.05% (50 mg/100 ml). You have not eaten since lunch.

1. Assess your fitness to drive and identify the legal issues.

There are two separate impairment issues, and the legal alcohol limit is only one of them. One 330 ml bottle at 5% contains about 13 g of alcohol; after 2.5 hours some will have been eliminated, but without a breath test you cannot assume you are under 0.05%. The bigger problem may be the cough syrup: codeine and chlorphenamine are sedating, and the drowsiness and dry mouth are signs of impairment. Even below the alcohol limit, driving while unfit through drugs is an offence. Your licence is still valid at 22:50, but your insurance expired three days ago, so you are not insured to drive - a separate offence.

2. What should you do now?

Do not drive to the checkpoint. Stop at the taxi rank 300 m behind you, park legally and lock the car, then take a taxi home. Collect the car the next day when fit and insured. Do not attempt to turn around suspiciously or “beat” the checkpoint; that attracts attention and can add offences. If you have already passed the rank, pull into a safe parking space before the checkpoint and call a taxi. The cost of the taxi is far less than the penalties for impaired driving and driving without insurance, and it removes the risk to other road users.

3. If an officer stops you, how should you respond and what documents matter?

Read the worked answer

Be polite and cooperative. Produce your driving licence and explain that the insurance renewal is on your phone but the certificate expired three days ago; do not claim cover you do not have. Answer questions about the beer and cough syrup directly. You may be asked to take a breath test or a field impairment test; refusing can carry its own penalties. Do not argue, offer money or try to talk your way past. Expect the vehicle to be prohibited and arrange a licensed driver or recovery. The documents that matter are your licence, insurance and vehicle registration; honesty about the expired insurance is better than a false claim.
