If you are driving along and you notice another motorist coming from the opposite direction flashing their lights at you, then it usually means a couple of different things.
You have either forgotten to put your headlights on, you have left your weekly shopping on your roof, or there is a speed camera in front of you
If you ride a motorbike and a fellow biker approaches you having just gone through a speed trap, then a hand gesture is normally given to alert the other biker.
Hand signals often used by motorcyclists
Of course, if you aren’t speeding, then you have nothing to worry about (assuming you are taxed, insured, MOT’d and have a valid driving licence).
But if you have crept over the speed limit, then this unofficial ‘warning system’ will not only slow you down, but it could potentially save you from having to spend £100 on a ‘speed awareness course’.
And let’s face it, motoring is already expensive!
But flashing your headlights at your fellow motorists to warn them about a speed trap could also land you with a £1000 fine.
But if this rule is taken literally, then it also means flashing your lights to let other motorists pull out of a junction could even land you in trouble.
Unlikely, but possible.
spots you doing it and they really want to throw the book at you, then they could technically fine/summons you for breaching section 89 of the Police Act 1997: “willfully obstruct a constable in the execution of his/her duty.”
The maximum fine for obstructing a police officer is currently capped at £1,000.
