UK Traffic Lights Explained: The Definitive Guide

You must proceed slowly and with caution and only continue when safe to do so. Advanced stop lines such as the images above allow for cyclists to stop ahead of other vehicles in a bay often in a alternative colour to the road. All traffic must stop at the first line when the lights are red and avoid entering the cycle bay when stationary. Do not enter that lane unless you want to go in the direction of the arrow.

A directional green filter arrow means that you have priority over traffic as their lights will be on red when you make the turn. As with all junctions be aware of pedestrians and cyclists whilst making the turn. Just because you have priority, there is a possibility of another vehicle, cyclist or pedestrian crossing or being where they shouldn’t be. Although understanding traffic the light sequences is reasonably simple, greater challenges often arise when dealing with other road users and pedestrians at traffic lights. It is of course important to obey traffic light signals, but equally important to have a constant awareness of what is around you. Cyclists and pedestrians in particular can be unpredictable around busy light controlled junctions.

What Does a Red Traffic Light Mean?

Running a red light is obviously dangerous and on may traffic lights, cameras are now fitted. There are very few exemptions for running a red light and even a learner driver may find themselves with 3 penalty points on their provisional licence and a fine of £60. A red light camera can even be triggered if your vehicle stops only slightly over the white line. Of course, this would also result in a driving test failure. If turning right and your green filter light is not illuminated or it distinguishes, you can still proceed providing the full phase green light is illuminated. You must however give way to oncoming vehicles and wait at the point of turn.

Light signals controlling traffic

TheMSPSL (Mirror, Signal, Position, Speed and Look) routine must be applied. A good level of anticipation and planning is also required. Also traffic lights at pedestrian crossings for instance, if in the distance you see people waiting, as you approach there is a high probability the lights will change. A green traffic filter light allows traffic to proceed in the direction of the arrow.

Whether you’re preparing for your DVSA theory test, revising the Highway Code, or simply brushing up on your road safety knowledge, the subject of traffic lights is vital. Traffic lights are a cornerstone of road safety, controlling traffic flow and ensuring motorists, cyclists, pedestrians, and other road users share the roads safely. Technically it’s not illegal to block a junction unless prohibitions are in force such as the yellow box. Other advisory notices such as ‘Keep Clear‘ road markings may also be in place. However, blocking a junction impedes traffic flow, so only enter it when you are certain you can clear it – even if your light is green.

You must obey any direction from a police officer or other authorised person. Signs may be placed with signals to qualify the meaning of the full green signal where movements through a junction are restricted. Take extra care if you intend to turn left or right, and give way to pedestrians who are crossing.

• A turning vehicle always has to give way to pedestrians who are crossing the road they are turning into, even if the pedestrian is not facing a green ‘walking figure’.
• However, many traffic lights do, especially at high-risk or busy junctions.
• Dealing with a traffic light failure can be daunting for a learner driver.
• Never remain inside the junction as you will stop the flow of traffic.
• Signs may be placed with signals to qualify the meaning of the full green signal where movements through a junction are restricted.
• Light signals used to control traffic, including traffic light signals, flashing red lights, motorway signals and lane control signals.

When a red and amber light appear at the same time, this indicates that the lights are about to turn green. Motorists can prepare to go, but they should not pass through until a green light appears. If a red light appears on the traffic lights, it’s a mandatory instruction that you must come to a complete stop behind the stop line. Under no circumstances should vehicles attempt to proceed or cross the line while the red light is visible. Failing to comply with a red traffic light is a serious offence that can result in penalty points, fines, and even prosecution in serious cases.

What Should You Do When Approaching Traffic Lights With Red and Amber Showing Together?

In most cases, in addition to the primary signals SRL solar panels at the stop line, there are duplicate signals, known as secondary signals, located on the opposite side of the junction. If the primary signal is not working, you must obey the secondary signal as if it were the primary signal. Low-level cycle signal may be used as a repeater or as an early release function mounted on the same post as a traffic signal or full-size cycle signal.

It is also relatively common for a learner driver to focus primarily on the red light and not notice the green filter light is illuminated allowing you to proceed. A filter light may illuminate before or after the full green phase. Ensure you keep an eye on the filter light as well as the main phase lights.
