No. From January 1, 2026, Euro 5 diesel vehicles (mostly registered 2011-2015) and Euro 2 petrol vehicles (pre-2001) are banned from the Brussels LEZ covering all 19 municipalities. You'll first receive a warning letter, then face €350 fines recurring every 3 months. Brussels aims to ban all diesel vehicles by 2030.
Belgium is rewriting its 50-year-old Highway Code with over 45 new traffic signs. Key changes include "square green" at intersections (cyclists and pedestrians cross in all directions simultaneously), cyclists can pass stationary traffic, motorcyclists may use the emergency lane in jams, and perpendicular parking is only allowed when explicitly signed.
Yes. The default speed limit outside built-up areas is 70 km/h in Flanders and 90 km/h in Wallonia. Brussels has expanded its 30 km/h zones across the city. Motorways are 120 km/h nationwide. From 2026, all speed cameras in Flanders operate permanently 24/7.
From July 7, 2026, all new cars must have Advanced Driver Distraction Warning (ADDW) - camera-based monitoring that detects phone use or inattention. Basic systems like AEB, ISA, lane-keeping, and drowsiness warning were already mandatory from July 2024 under EU GSR2.
