But did you know these nine common driving habits are actually illegal?

5. Sleeping in your car when drunk
The law states that those in charge of a motor vehicle should not be inebriated, which means you could still be charged with a driving offence for sleeping in your car drunk.

6. Using your phone as a sat nav in an unfixed position
It is illegal to use a hand-held mobile to follow a map. You must fix it to your windscreen or dashboard in order to use smartphone navigation or a mapping app. You could receive a 200 fine and six points on your licence if caught in the act.

7. Driving with a dirty number plate
Registration plates must be visible at all times when a car is on the road. If your number plate is dirty and one or more of the numbers or letters on your plate can't be read, then you could be hit with a hefty fine.

8. Splashing pedestrians
It is illegal to splash someone as it amounts to driving without reasonable consideration for other persons. Those found guilty can face fines of up to 5,000 or even three points on their licence.
