10 official questions to revise this topic before the DGT exam.
Speed-limit questions in the DGT theory test for Permit B look simple at first — just memorise the numbers — until you find out that each road type has its own generic limit, that the limit changes by vehicle type (car alone, car with light trailer, car with heavy trailer), and that special conditions override the obvious: urban streets capped at 30 km/h on single-lane-per-direction roads, motorways and expressways limited to 100 or 80 km/h in roadworks or bad weather, and conventional roads where the limit depends on whether there is a shoulder. Beyond the numbers, the exam asks about adequate speed — the speed that lets you stop within visible distance — and the penalties for exceeding limits. This quick test gathers ten representative questions from the 2026 official DGT bank covering generic limits, adequate speed, weather conditions and penalties. Every answer comes with an explanation; when you finish you'll see related topics worth revising too (speed signs, alcohol and drugs, traffic rules).
