Most driving offences are pretty black and white, but what about the ones we don’t realise are illegal?

Here are 10 ways you could be breaking the law without being aware you’re doing so.

1. Sleeping while inebriated in your car

If you’ve had too much to drink you obviously won’t be driving but what if you took your car to get there in the first place?

If you decide that you will just sleep in the car until you are sober enough to drive then you could be caught, opening yourself up to a drunk in charge fine. You should not be in charge of a vehicle, moving or not moving while inebriated.

2. Flashing your lights to give way

Many of us will commonly use them to allow other drivers through gaps, but this technically could be considered a driving offence if an accident resulted from it. Headlight flashes should only be used to warn drivers of your presence on the road.

3. Overtaking at a pedestrian crossing

Coming up to a pedestrian crossing on a multi-lane road? Is there a car already stationary there? If the lights then change to green, do not use your extra momentum to zip past the stationary car - this is illegal.

You must not overtake the car nearest to the pedestrian crossing. Why? Because their vehicle may be concealing a pedestrian already on the crossing.

4. Letting animals out of the car while broken-down on the hard shoulder

The Highway Code clearly states that you must leave any animals in a broken-down vehicle when stranded on the hard shoulder. Only in an emergency should you consider letting them out - if you don’t obey this and an accident is caused by your animal on the hard shoulder, you could face a driving offence charge.

5. Parking on the wrong side of the road at night

Motorists should not park on the wrong side of the road at night. This is not, as some may think, because you have to drive on the opposite side of the road both to enter and leave the space, actually it’s because of the risks of dazzling. You’ll both dazzle other drivers with your headlights as you park and leave, while your rear light reflectors will also not be visible once you’ve left the car. This is a driving offence under rule 248 of the Highway Code and can receive a Penalty Charge Notice.

6. Using your mobile phone as a sat nav in an unfixed position

The mobile phone law specifically refers to using your phone as a sat nav, stating it is illegal to use a handheld mobile to follow a map.

In order to use smartphone navigation or a mapping app, the phone must be fixed to the windscreen or dashboard (preferably the dashboard as to not impede the driver's view), so it’s in clear sight for use while driving, without requiring you to hold it.

The mobile phone and driving laws have changed and if you are caught breaching them you will now receive a £200 fine and six points on your licence, which would be enough to get a new driver - who has had their licence for less than two years - banned.

7. Parking within 10 metres of a junction

Parking too close to a junction makes it harder for everyone - those approaching the junction have to steer around the car, and those turning into the junction risk driving into an unsighted car on the wrong side of the road. Therefore, it is a driving offence, so don’t commit it.

8. Driving on the pavement unless you’re turning into a driveway

Rule 244 of the Highway Code states that you must not park fully or even partly on the pavement unless road signs permit it: in London, it’s an offence to park on the pavement, full stop.

This is perhaps one of the most common Highway Code rules broken and, if you’re parked in a way to inconvenience pedestrians, you’re causing a driving offence.

9. Using the horn between 11.30pm and 7am in a built-up area

It seems like taxi drivers do it all the time - beeping the horn late at night. But it’s actually illegal - and this includes a short parp when waving to the family during your early-morning start.

It’s unlikely the police would charge you if caught, but it’s still a driving offence you may not be aware of.

10. Driving at more than 50mph in a van on a single carriageway road

This is a rule that catches many people unawares. Vans that aren't car-derived must not exceed:

50mph on single carriageways

60mph on dual carriageways

70mph on motorways

So don’t try to keep up with the flow on single carriageways, as you’ll be breaking the law. On dual carriageways, the limit is 60mph, but these vans are allowed to do 70mph on the motorway.
