Driving the next day after a few drinks.

 ·  Posted: 28.12.2019  ·  #1
Folk, if I may, can I bring some clarity to the mis conception of drink in the body the morning after.... a bottle of white wine will need 9 hours to work it's way free from the breathalyzer from the time you finish the last drop. A pint of stout is 2.3 units each, so 6 pints is 14 units give or take, so that's 14 hours after you finish the last pint. 1 whiskey is 1 unit, so half a bottle is 15 units, so that's 15 hours after you finish the last glass. I've heard lads thinking that the body clock starts 1 hour after you start drinking! Don't get codded, the body clock only starts when you finish the last drop, and bare in mind the units you took on board determines the length of time you need to stay away from behind the wheel the next day. Hope this info helps.

CLICK HERE for a very useful calculator and note that the time taken to get back to zero Blood Alcohol Count (BAC) starts from the first drink, not the last.

Our current legal limit of 50 mg of alcohol per 100 ml of blood = a BAC of 0.05%
For professional, learner and novice drivers it's 20 mg of alcohol per 100 ml of blood = a BAC of 0.02%

And the limit of 20 mg shall apply if you cannot produce your license on the spot.

Good information but you also need to consider body weight,mass etc as everyone process differently. The breathalyser is good but only a guide. Companies used to call me in to do spot checks for drugs and alcohol and the device needed calibrated on a regular basis to be accurate. I think common sense is best.

Some good info there. I tried a live test using the calculator from Baguette's post, and using the International Brewers and Distillers rule of thumb to allow an hour per unit once finished drinking, and used an analyser from Halfords. Here's the results with all methods.
Started drinking at 7pm Saturday night and stopped at 11pm. I drank 4 pints of Guinness and 2 whiskeys. = 11 units in total in the 4 hours.
Calculator says I need 10 hours to return to BAC, so I'd be safe at 9am next morning. I registered 0.31 on the analyser at 9am.
IBD rule of thumb suggests 11 hours to return to BAC, so that's 10am next morning. I registered 0.20 on the analyser at 10am.
I registered 0 at 11:30am on Sunday morning.
TommyS gives good advice....common sense is best, once you know there's driving to be done the next day.
Happy New Year to you all, and hope to meet you on the roads throughout the coming year.

We carry a breathalyser as well and never move of until is says safe I test myself every hour and when it says safe I give it an extra hour just in case
