300 yards to a roundabout or the next point at which traffic may leave a non-primary route
Countdown sign telling you a roundabout or major exit is exactly 300 yards ahead on a non-primary route. You now have plenty of time to check mirrors, signal, and move into the correct lane smoothly. Non-primary routes are usually A or B roads that are not the main trunk roads, so traffic flow can be less predictable. Use this warning to begin planning your exit and positioning early – a common theory-test mistake is leaving lane changes until the last moment, which can cause sudden braking and increase the risk of rear-end collisions.
