FIREFIGHTERS have warned drivers they could still be over the drink-drive limit, 'even if they feel fine'. 

Oxfordshire Fire and Rescue says 'time' is the only way of getting alcohol out of your system - drinking coffee, sleeping or having a shower 'doesn't work'. 

But how long should you wait to drive after drinking? 

Emergency services have put together a handy guide so drivers can calculate how long they need to wait before getting behind the wheel after drinking alcohol.

For every drink, the time doubles, but drivers need to add an hour before setting off. 

Here are a few examples: 

  • For one glass of wine you will be okay to drive after 4.5hours. 
  • For one pint of 4percent beer you will be okay to drive after 3.5hours. 
  • For a single shot you will be okay to drive after 2.5 hours.
  • For two glasses of wine and a shot you will be okay to drive after 9.5hours.
