The most common traffic sign offence is running a red light. A driver is just as likely to be stopped by the police at the time of the offence as he is to be caught on camera. Either way the offence is usually dealt with by a Fixed Penalty of 3 points and a fine of £100.
The obligations on a driver when approaching a set of traffic lights can be summarised as follows:
- If the traffic lights are showing a red light the driver must stop behind the white stop line in all circumstances.
- If the amber light is illuminated the driver must stop, unless he has already passed the stop line or to do so would be unsafe.
The obligation is clear, the driver must stop unless the light is green, in which case he may proceed if it is clear and safe to do so. It should be noted that the offence is committed if any part of the vehicle crosses over the stop line when the red light is showing. The offence is committed even where the car is stopped before the rear wheels go over the stop line.
If the white stop line is worn out and otherwise not fully visible the driver should stop in line with the primary signals. The same principal applies to temporary traffic lights with no stop line. In these circumstances, however, there should be a sign stating “when red light shows wait here”. The position of that sign is regarded as the stop line and the offence is committed if that point is passed when the red light is showing.
