Check your mirrors, brake in good time and leave enough room behind the vehicle in front. When approaching a red traffic light, you should follow all the usual rules for pulling up. Some junctions therefore use traffic cameras to catch people jumping the lights those caught can be issued a fine and risk points on their licence. It’s a serious offence to run a red light, because it puts you and other road users at risk. So, when faced with a red traffic light, you aren’t allowed to go through it. In driving, the colour red means you're prohibited from doing something.

But let's delve a bit deeper into the rules so that you won't get caught out on the roads. Or Flashing Amber (give way to pedestrians go if it's safe to do so)Īmber (Stop unless it's not safe to do so) The basic sequence contains four phases, and each has a separate meaning.

We'll also explain green filter arrows and why you shouldn't move through a red light-even for an emergency vehicle.
TRAFFIC LIGHT DURATIONS FULL
To help you on your way, we'll take you each phase of the full traffic light sequence, including flashing amber lights. Traffic lights play a vital role in controlling traffic flow and preventing accidents, and to do that effectively they need to be properly understood. But for your theory and practical tests, a general idea just won't cut it. Take traffic lights: we see them so frequently that it's easy to take for granted that we know what they mean. But don't neglect the common ones, because they're equally important, and just as likely to trip you up. In order for the traffic signals to be synchronized, a group of signals must all be set to run on the same cycle length (the amount of time it takes for the signal to go from green to yellow to red and back to green again - after the cross street has been serviced.As you learn the rules of the road, it's natural to get hung up studying some of the more obscure road signs and symbols. The way traffic signal synchronization works is by calculating the arrival time for a group of vehicles at each intersection traveling at a specified speed, and then the traffic signals are strategically timed to turn green just as the group of vehicles arrive at each intersection. The goal of synchronization is to get the greatest number of vehicles through the intersections with the fewest stops. Hence, it is beneficial for both the main street and side street traffic. However, synchronizing signals along a main street can benefit all motorists because once a vehicle enters the main street, it may continue with minimal stopping.
TRAFFIC LIGHT DURATIONS DRIVERS
If the traffic on a main street is considerably higher than the side street, more green time may be given to the main street which could result in a longer wait for drivers on the side street. Traffic signals are designed to distribute the green time to conflicting traffic streams, generally based on the traffic volumes.
Why signal synchronization is neededĭrivers often get frustrated when they have to stop at successive traffic lights, or when they have to wait a long time for a green light, especially when there appears to be no traffic in the other directions. Synchronizing traffic signals ensures a better flow of traffic and minimizes gas consumption and pollutant emissions.
TRAFFIC LIGHT DURATIONS SERIES
Traffic Signal Synchronization is a traffic engineering technique of matching the green light times for a series of intersections to enable the maximum number of vehicles to pass through, thereby reducing stops and delays experienced by motorists.
