Belgium for Polish Drivers — the 140-to-120 Drop & Camera Belt

For Polish drivers, Belgium is an easy fit on paper — EU licence, right-hand traffic, euro fuel. The thing that actually costs people money is speed, because Belgium runs slower than Poland and watches the difference closely.

The motorway speed drops, and the cameras log it

At home you cruise motorways at 140 km/h. In Belgium the limit is 120, and this is not a number you can stretch. Long motorway sections use average-speed (section) cameras that time you between two points, so a brief overtaking burst still counts. Drop into the 120 habit from the first slip road; 10 km/h over runs about EUR 53, and you can model it on the Speeding Fine Calculator. Rural roads are 70–90, town 50, and central Brussels is 30.

Priority to the right is enforced

Belgium applies priorité à droite firmly. At an unmarked junction a vehicle from your right has priority, even on a road that feels like the main one — locals will pull straight out. Watch for the yellow priority diamond; where it’s missing, yield to the right. The Brussels ring (R0) is the worst place to learn this, with fast lane changes and little patience.

Looser alcohol, but don’t lean on it

The alcohol limit is 0.05, more relaxed than Poland’s near-zero 0.02 — but roadside breath tests are routine and a fail means an on-the-spot fine and possible ban, so treat it cautiously. No IDP is needed (confirm via the Driving Permit Checker), the car must carry a triangle, vest, first-aid kit and extinguisher, petrol is about EUR 1.90/litre, and emergency is 112. Signs switch between Dutch, French and German by region. Full rules sit on our Belgium driving guide.
