Research suggests over three-quarters of UK drivers never return to the highway Code bible after passing their test!

Are you one of the thousands of drivers who contravene these most-forgotten road rules every day?

Is the Highway Code actually law?

No, taken alone the Highway Code is not the law. But many of its instructions are backed up by law and therefore have legal muscle behind them.

Those points supported by the law are clearly identified in the document by wording like ‘MUST’, ‘MUST NOT’, rather than ‘should’ or ‘should not’.

Failure to comply with the other rules of the Code can’t directly cause you to be fined, prosecuted or disqualified – but the advice it offers can be used as evidence in any court, to establish liability.

1. ‘Undertaking’

According to the Code, overtaking on this side is acceptable if you’re on a multi-lane carriageway in congested conditions, meaning the left lane is moving faster than the right.

It’s also OK if the vehicle in front is signaling to turn right.

Still this hardly accounts for all those times someone whooshes by you on the inside before you’ve had a safe chance to pull back into lane one.

There is no law itself against the act of undertaking, but it can count as an offence under careless or even dangerous driving.

2.  ‘Hogging’ the middle lane

Middle-lane hogging is one of the biggest bugbears among drivers. It’s when vehicles remain in the middle lane longer than necessary, even when there aren’t any vehicles in the inside lane to overtake.

Many argue it’s safer to remain on a straight course than weaving in and out of lanes, and certainly common sense is generally applied by both drivers and the police.

But ultimately, rules are rules – the Code implicitly states you should return to the left-hand lane as soon as you safely pass.

New laws introduced in 2013 give police officers the power to hand out on-the-spot fines of £100 and three penalty points for middle-lane hogging.

3. waiting or parking on yellow zig zags

Found outside entrances to schools, hospitals, police and fire stations, these areas are to be avoided for everyone’s safety.

You will not, however, be issued a Penalty Charge Notice (PCN) unless these lines are accompanied by a sign, detailing the restriction.

Sign or not though, it is never advisable for motorists to park on these restrictions.

4.  Crossing double (center-of-road) white lines

We’re forbidden by law from crossing double white lines in the middle of the road where the line nearest to us is solid. Still how many times do you see drivers straddling, or even pulling out into the oncoming lane?

The curveball here is that this practice is actually allowed in certain circumstances – although rarely the ones in which the rule is broken.

You can cross the lines if entering adjoining premises or a side road, or if safe, to overtake a pedal cycle, horse or road maintenance vehicle travelling at 10mph or under

5.  In-car distractions

We’re all aware of the legal requirement to Be Phone Smart and keep hands well and truly off our mobile phones while in control of our vehicles. But how many of the Highway Code’s list of distractions to avoid are we squeaky clean on?

The Code reminds us that safe driving needs concentration, and to ‘avoid’ the following distractions when driving:

• loud music (this may mask other sounds)
• trying to read maps
• inserting a cassette or CD or tuning a radio
• arguing with your passengers or other road users
• eating and drinking
• smoking

In short, we’re regrettably probably all guilty of violating the Code on this front from time to time.

6.  Holding up long queues of traffic

We’re probably more likely to say we’re the victim, rather than the perpetrator of this Highway Code no-no, but it’s regularly not followed.

It’s a particular problem among larger or slower-moving vehicles, which are politely asked to frequently check their mirrors and pull over – if necessary and safe – to let traffic pass. Do they always though?

7.  Always let out buses

The Code tells us to give priority to buses, coaches and trams when you can do so safely – particularly when they’re signaling to pull away from stops.

The truth is, it isn’t a legal requirement. Buses must indicate and wait for a gap in traffic like the rest of us.

But not only is it courteous to safely slow down and leave a good distance as soon as you see a larger vehicle’s signal, it also avoids confusion and the possibility of a large bus pulling into your path.

A related misdemeanor comes with use of bus lanes. As sensible as it might feel to use one to ease congestion when there’s not a bus in sight, you can and will be punished if you stray during times of operation.

This one’s law, and increasingly cameras are placed to target it. The typical punishment for driving in a bus lane is £130 in London and £70 outside the capital. Prompt payment can usually mean a half-price reduction

8.  Use your parking lights at night

All vehicles must display parking lights – sidelights – when parked on a road (or lay-by) with a speed limit over 30mph.

If the road has a speed limit of 30mph or less, you don’t need to leave on your sidelights, as long as your spot is a recognised parking bay or lay-by, or you’re facing in the direction of the traffic flow, close to the kerb, and at least 10 meters from the nearest junction.

This one’s law, and you’re technically eligible for a fine if caught – although a common sense is often applied by the police

9.  Hands off that horn!

Another widely-ignored law found in the Code centers on inappropriate horn use. While many drivers tend to use their horn in times of frustration, the Code says it should only be used to warn other road users of our presence, and shouldn’t be used ‘aggressively’.

It adds that you MUST NOT use your horn while stationary on the road or when driving in a built-up area between 11.30pm and 7.00am.

10.  Turn off your fog lights

Fog lights are only to be used when visibility is “seriously reduced”. This is usually taken to mean when visibility is less than 100 meters.

Leave them on as a luxury when visibility improves and you might dazzle other road users, breaking the both the law and the Highway Code in the process.

11.  Keep your distance in tunnels

Another that passed a few of us by. If you have to stop in a tunnel, you’re encouraged by the Code to leave at least a 5-metre gap between you and the vehicle in front, primarily to account for the reduced or altered visibility levels.

The obvious problem here is that this becomes difficult if traffic has been slow and more ‘nose-to-tail’ before a stop is necessitated. Still, be wary as it’s in the Code

12.  Driving over painted mini-roundabouts

Another we’ve probably all been guilty of. When faced with just you and the road ahead, making a deliberate circle can seem a tad pointless.

Understandably though, it’s not acceptable practice under the Code, and remains one of the most widespread misdemeanors on local roads.

This one is law and you could be subject to a Fixed Penalty Notice if caught, leave a comment below if this has happened to you

13.  Inadequate (or excessive) indicating

We use our indicators to advise other road users before we change direction, stop or move off.

But as we know, there are several ways in which incorrect indicator use can cause confusion – from failure to signal, forgetting to cancel it after a turn, and signaling too early or too late.

We’re reminded that “signaling does not give you priority” – and not to assume that someone will allow us space just because we want to move into it. Solid advice

14.  Turn off your engine if parked

Even if you’re just popping out for a couple of minutes, you can’t leave a parked vehicle unattended with the engine running, or leave it running unnecessarily while stationary on a public road.

OK, you wouldn’t really want to do this anyway for fear of someone jumping in and heading off in your pride and joy – but so you know, it’s against the law. One to remember when warming up the car on an icy morning – don’t get fined for de-icing your car

15.  Flashing headlights inappropriately

The Code states we should only ever flash headlights to let other road users know that we’re there – never to intimidate or try to convey any other sort of message.

Importantly, we should never make the assumption that another driver flashing their headlights is a signal inviting us to proceed. We’ve all heard of ‘flash for cash’ scams. Use your best judgement and proceed carefully

16.  Check before opening a door

The Highway Code states “you MUST ensure you do not hit anyone when you open your door. Check for cyclists or other traffic.”

Funny then that between 2011 and 2015, there were 3,108 reported collisions where a “vehicle door opened or closed negligently” was recorded as a contributing factor in incidents attended by the police.
