10 Especially Important Numbers for the Theory Test
Speed Limit in Built-Up Areas
Maximum speed of 50 km/h within built-up areas
Speed Limit on Country Roads
Maximum speed of 100 km/h on rural roads without specific signage
Recommended speed on the highway
130 km/h – not mandatory, but the recommended speed on German highways
Safety Distance
Half the speedometer reading—that is, at 100 km/h, your following distance from the vehicle ahead should be at least 50 m
Distance When Passing Cyclists
At least 1.5 m within a built-up area, at least 2 m outside a built-up area
Parking Distance from the Bus Stop
Parking is prohibited within 15 meters of bus stop signs, both in front of and behind them
Minimum Tread Depth of Tires
At least 1.6 mm—anything less than that means a tire is no longer considered safe for the road
Rear fog light
Turn on the fog light only when visibility is less than 50 m, such as in heavy fog.
Protruding Cargo
Loads that protrude must be marked when they extend more than 40 cm to the side and more than 1 m to the rear
Braking distance
When the speed doubles, the stopping distance quadruples: at 50 km/h, it is 25 m; at 100 km/h, it is 100 m.
