The party is over, but the alcohol isn’t: Why the morning after is the greatest risk to your licence this Christmas.
As the office party season heats up, thousands of drivers will make a catastrophic mistake by getting behind the wheel the morning after, unaware they are still over the legal limit. An estimated 28% of drivers admit to having driven when they thought they might be over the limit the next day. The penalties for a morning-after conviction are identical to those at midnight: a mandatory minimum 12-month driving ban, an unlimited fine, and a criminal record. Protect your licence, livelihood, and freedom by understanding the rules of alcohol metabolism this festive season.
While many associate drink driving arrests with late-night stops, data shows a significant spike in arrests the following morning. Annually, an estimated 5,500 drivers fail breath tests administered between 6:00 am and midday across the UK. With December consistently ranking as the second-worst month for drink-drive collisions (behind August), the risk during the festive season is particularly acute, often due to drivers misjudging their fitness to drive after a heavy night.
Shazia Ali, CEO of Scarsdale Solicitors and an expert in motoring law, offers crucial advice to professionals attending festive celebrations. She says:
“The biggest myth we see in motoring defence is that a few hours of sleep clears your system. It doesn’t! Your body metabolises alcohol at a rate of roughly one unit per hour, and nothing – not coffee, a cold shower, or a heavy breakfast – will speed up this process.

If you have an office party or a heavy night of drinking:
- Time is the Only Cure: The safest rule is to allow at least 12 hours after your last drink before considering driving. If you finish drinking at 3:00 am, you may still be over the limit at 9:00 am or even later.
- Plan Non-Driving Transport: If you have drunk alcohol, assume your car is unavailable the next day. Arrange for a taxi, public transport, or a lift, even for short trips like the school run or commute.
- Do Not Risk It: Do not rely on how you ‘feel’—you could feel perfectly fine but still be over the legal breath limit (35 micrograms of alcohol per 100 millilitres of breath in England, Wales, and Northern Ireland). If you are in any doubt, do not drive.
- Double Check Medicines: Make sure you read all the small print on any medicines you are taking, whether prescription or over-the-counter. Does it say not to mix with alcohol? Does it warn it may make you drowsy? Alcohol can exacerbate the sedative effects of certain drugs so ensure you are not putting yourself at risk of breaking the law.
- Don’t Rely on Old Wives’ Tales: Finally, ignore the persistent myths you hear online or in the pub. Sucking a copper coin, eating an onion, or smoking a cigarette will not, absolutely cannot, help you dodge a breathalyser. These devices are high-tech, evidential instruments calibrated to measure alcohol accurately. They are not simple gadgets that can be fooled or cheated by simple tricks. Your only solution is time.
