What is B.A.C?

B.A.C. stands for Blood Alcohol Concentration and is a measure of the amount of alcohol in your blood. Your B.A.C. begins to rise the moment you start drinking and will usually take an hour after your last drink to reach its highest level. A heavy night of drinking could take up to 18 hours to leave your system.

Alcohol behind the wheel - How alcohol impares your driving performance

  • Speed is difficult to judge
  • Encourages sleepiness
  • Colours can blur together
  • Surroundings become fuzzy
  • Sounds become distracting
  • Distances harder to judge
  • Limits co-ordination

The penalties

What are you facing when driving under the influence?

  • Heavy fines
  • Drug and alcohol rehab
  • Loss of demerit points
  • Vehicle breathalyser lock
  • Lose your licence
  • Lifetime ban from driving
  • After hours driving curfews
  • Time in jail

Myths busted

All of these myths claim to hide alcohol on a driver’s breath - and all of them are false. Breathalysers are way smarter than that and can always detect alcohol when it’s present.

  • Suck on a battery
  • Drink loads of coffee
  • Spray breath freshener
  • Chew gum

These myths lull people into a false sense of security.

  • Delay breathalyser test
  • Sleep it off

It’s always better to be safe than sorry. And remember - alcohol stays in your system for up to 24 hours.
