1. Traffic jam
A traffic jam is a situation where traffic becomes heavily congested and vehicles move very slowly or stop for extended periods. Traffic jams are commonly caused by high traffic volumes, accidents, roadworks, lane closures or poor weather. Drivers should remain patient, keep a safe distance, avoid unnecessary lane changes and watch for motorcycles, emergency vehicles and sudden braking. Where lanes merge during congestion, local rules may require drivers to use a zipper-merging system.
Is there a traffic sign for traffic jams in Belgium?
Yes. Under the currently applicable Belgian Road Code, warning sign A50 warns of a traffic jam. It does not set a numerical speed limit. Slow in good time, maintain sufficient distance and be ready to stop for a queue.

Do drivers have to create an emergency corridor in a traffic jam in Belgium?
Yes. When a traffic jam forms on a road with at least two lanes in the same direction, drivers must create a rescue lane. Drivers in the left lane move as far left as possible, while drivers in the other lanes move as far right as possible.

When do you have to zipper merge in Belgium?
In heavily congested traffic, when a lane ends or becomes blocked, drivers in that lane must continue until just before the narrowing and then merge into the adjacent lane. Drivers in the continuing lane must alternately allow one vehicle to merge.
