Traffic lights warningItaly
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 Italy?
The warning-sign system commonly uses a red-bordered triangular sign with a traffic-light symbol. The precise design and placement depend on the national traffic-sign schedule. This warns of a signal ahead; it is not itself a red traffic light.

Does a traffic-lights-ahead warning require an immediate stop in Italy?
No. A warning sign is not an automatic STOP instruction and does not create a new numerical speed limit. Reduce speed when necessary, look for a queue or a concealed signal, and obey the traffic lights and any separate speed or stop signs.

What should you check if the next traffic lights are difficult to see in Italy?
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.
