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.”
The Department of Transport claim that a breach of Rule 110 and 111, which outline the rules of motorists flashing their headlights, could stand up in a court of law as evidence.
While alone that is not to see the motorist convicted, if drivers were using their headlights to warn a motorist of a speed trap then it could be breaching another road law. Section 89(2) of the Police Act 1996 outlines what can happen if motorists obstruct an officer.
It says: “Any person who resists or wilfully obstructs a constable in the execution of his duty, or a person assisting a constable in the execution of his duty, shall be guilty of an offence and liable on summary conviction to imprisonment for a term not exceeding one month or to a fine not exceeding level 3 on the standard scale, or to both.”
It could be argued that a motorist warning other drivers of a speed trap could be ‘obstructing’ an officer.
