Learning how to drive in the UK? It’s an exciting phase for you but it also comes with challenges that can be overwhelming at first. There is one scenario on the road layout that often confuses learners is the contraflow system.
If you’re preparing yourself for either a practical test or a 1 Week driving course in London, understanding contraflow is of utmost importance. While it is normal that these systems may look scary initially, they are actually quite simple if you know how to approach and understand them.
In this blog, we will talk about everything you need to know about contraflow systems, including what they are, practical tips, and how you can be on the right track. Let’s get started.
What Is a Contraflow System?
A contraflow system is a particular type of road layout in which the vehicles are directed to move in the opposite direction of the usual flow on a section of the carriageway. The term “contra” means against, while “flow” is short for the flow of traffic. So when traffic is said to be “contraflow”, it means that the mode of transport is moving against the already set direction.
These systems may be:
- Temporary: Often seen on motorways and dual carriageways during roadworks, emergencies, or accidents.
- Permanent: Used in urban areas to allow buses or cycles to travel opposite to one-way traffic.
Where You’ll Encounter Contraflow Systems
Contraflow systems are commonly found in:
- Roadworks on Motorways: If part of a motorway is closed due to maintenance, traffic may be diverted onto the other carriageway. Be prepared for narrow lanes, lowered speed limits, and the presence of temporary cones or barriers.
- Urban Bus Lanes: Contraflow bus lanes allow buses to go against the flow on one-way streets. Such lanes have clear markings with a blue sign.
- Cycle Lanes: In city centres, contraflow cycle lanes allow cyclists to go against traffic on one-way streets so that journeys can be easy and safe.
Tip for Driving Through a Contraflow System
If you are attending a 1 Week driving course London or training by yourself before the exam, here are some handy tips:
- Spot the Signs Early: Make sure to look for temporary road signs showing a contraflow ahead. During temporary setups, they are generally on a yellow background.
- Be in Your Lane: If you are in a contraflow, especially on motorways, change into the correct lane early and remain there. The prohibition on overtaking is for safety purposes.
- Take Care of Your Speed: Contraflow areas often have lower speed limits for safety. Sticking to them shows good judgment during your test.
- Give Space: Narrow lanes and traffic in close proximity always mean keeping a safe distance from other vehicles.
