No one likes getting caught by a speed camera which means usually if you spot a new camera its just instinct to tell others about it if youre having a conversation, perhaps approaching the road that it is located on as a passenger in a car.
However extending a well meant warning other drivers using the same road as you by flashing your headlights could land you in hot water!
The Highway Code states you should only flash to let other drivers know you are there and doing otherwise could potentially prevent police officers from doing their job
Rule 110 states: “Only flash your headlights to let other road users know that you are there.
“Do not flash your headlights to convey any other message or intimidate other road users.”
This means that drivers do choose to flash to warn others about a speed trap implemented by the police, they could be in breach of section 89 of the Police Act 1997 .
Under this law it states that it is an offence to “wilfully obstruct a constable in the execution of his/her duty.”
If the police deem you are obstructing their ability to perform their speed checks on other motorists you could be slapped with a maximum penalty of £1000.
