While you may think that you’re being a courteous driver by flashing your headlights to let other motorists pass, you’re actually breaking a key rule. Flashing your headlights should only be done in specific circumstances as outlined in the Highway Code, and if you defy these guidelines you could end up with a hefty fine.
Rule 110 of the Code states that you should “only flash your headlights to let other road users know that you are there”.
The rule goes on to say: “Do not flash your headlights to convey any other message or intimidate other road users.”
In a similar vein, the Code also warns drivers that they should “never assume that flashing headlights is a signal inviting you to proceed”, adding: “Use your own judgement and proceed carefully.”
Plenty of drivers will also use their headlights to warn others of an upcoming speed camera. However, doing this could land you with a fine of up to £1000, according to We Buy Any Car.
Car dealership Dick Lovett explains that this is because you would be seen as “obstructing police duties” under section 89 of the Police Act 1997. It states: “While it might feel nice to help and look out for a fellow driver, it could lead to more reckless drivers on the road if they’re not caught by police and fined accordingly. Remember, speed limits are there to keep everyone, including you, safe.”
Headlights are mentioned in several other Highway Code sections, including Rule 113, which states that drivers must ensure all sidelights and rear registration plate lights are lit between sunset and sunrise.
It also says drivers must “use headlights at night, except on a road which has lit street lighting” and “use headlights when visibility is seriously reduced”. If you fail to follow these rules, you could end up with a fine and points on your licence.
However, drivers must not use lights “in a way which would dazzle or cause discomfort to other road users, including pedestrians, cyclists and horse riders”. It is also against the law to “use front or rear fog lights unless visibility is seriously reduced”, under Rule 114.
The Highway Code explains that if drivers are in traffic that isn’t moving, they should be careful with how they use their brake lights. It says: “In stationary queues of traffic, drivers should apply the parking brake and, once the following traffic has stopped, take their foot off the footbrake to deactivate the vehicle brake lights. This will minimise glare to road users behind until the traffic moves again.”
