Hız sınırları ve kontrol
- 1/20If driving in urban areas
This limit ensures safety for pedestrians and other vehicles. Speeding in urban areas carries heavy fines.
When driving on two-lane rural roads
Lower speeds reduce risk on narrow roads with limited shoulders.
If driving on divided highways
This speed maintains stability while allowing safe traffic flow.
When driving on motorways
Motorway speeds are set to balance efficiency and safety for trucks.
If road signs indicate lower speeds
Temporary limits (e.g., 30–50 km/h) override general rules for safety.
When descending steep hills
Using engine braking keeps speed within safe and legal limits.
If approaching curves
Reducing speed before entry prevents skidding or rollover.
When approaching intersections
Slower speeds improve reaction time for crossing traffic.
If road surface is wet or icy
Reduced speed prevents sliding and loss of control on slippery roads.
When carrying heavy or tall loads
Heavier loads need lower speeds for stability and stopping distance.
If overtaking on highways
Trucks cannot exceed the legal maximum even during overtaking.
When approaching pedestrian crossings
Slow speeds protect vulnerable pedestrians and allow emergency stopping.
If driving in poor visibility
Adjust speed to allow stopping within the visible range ahead.
When towing a trailer
Towing reduces stability, so lower speeds are required.
If approaching a school zone
Lower limits protect children during arrival and departure times.
When approaching sharp bends
Slowing down prevents loss of control on tight turns.
If using cruise control
Curves, rain, or traffic require manual control regardless of limit.
When approaching construction zones
Lower speeds protect road workers and adjust for narrowed lanes.
If downhill braking frequently
Prevents brake overheating and loss of stopping power.
When exiting highways
Exit speeds are designed for truck stability and safe cornering.
