Police spotting (junction watch)

Myth Busting

Myth: There’s a car in the ASL box - the driver must have committed an offence.

Not true. The offence is committed when the vehicle enters the ASL box when the light is red. If the vehicle enters the box and the light changes to red, no offence is committed

Rule 178 of the Highway Code states:
If your vehicle has proceeded over the first white line at the time that the signal goes red, you MUST stop at the second white line, even if your vehicle is in the marked area.

We don’t want motorists to wrongly believe that they shouldn’t stop in the ASL box under any circumstances – this might cause someone to panic, drive through a junction and cause an accident.

patronise much?
