Touring took a snapshot of the motorists on the Brussels and Antwerp ring roads, the Ostend Brussels, the Brussels Antwerp and the E411 motorways. A fifth of all drivers had faulty lights or no lights at all.
The figures show that the situation has deteriorated since Touring carried out a similar investigation 5 years ago.
Touring's Danny Smagghe says that many drivers forget their lights or can't use them because they are faulty: "Too often motorists rely on their automatic dipped headlights but too often they do not function. Some systems are more sensitive than others. Sometimes the sensors don't trigger the lights when they really should."
