Traffic lights warningColombia
1. Traffic lights warning
A traffic lights warning is a warning sign that alerts drivers that traffic signals are located ahead. It is commonly used where the signals may be unexpected, difficult to see from a distance or located on a road where drivers need additional time to prepare to stop.
Drivers approaching a traffic lights warning should reduce speed when necessary, watch for the signals ahead and be prepared to stop if the traffic light changes or traffic is waiting at the intersection.
How are traffic lights ahead warned of in Colombia?
A yellow warning sign showing a traffic-signal symbol can alert drivers to traffic lights ahead; the exact shape and application follow local sign standards. It warns of a potential need to stop, but does not replace the actual signals.
Does a traffic-lights-ahead warning require an immediate stop in Colombia?
The warning alone does not require an immediate stop. However, Article 74 requires drivers to reduce speed to 30 km/h when approaching an intersection. Obey any lower limit, the actual traffic lights and applicable stopping or priority duties. Look for queues and be prepared to stop.
What should you check if the next traffic lights are difficult to see in Colombia?
Allow enough distance to stop before the marked line, watch for vehicles braking suddenly and be ready for a pedestrian or cyclist crossing. If the signals are out of order or flashing, follow the applicable local failure and priority rules rather than guessing from the warning sign.
