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.
Can Hungarian drivers weave through continuous queues?
No. In dense continuous queues, lane changes are restricted to preparing to turn or stop.
