In urban zones, trucks must follow a default limit of 50 km/h, with frequent reductions in school or pedestrian areas.

Spanish industrial estates often reduce limits to 30 to 40 km/h for safety due to frequent pedestrian and vehicle activity.

Heavily loaded trucks must reduce speed to avoid rollover risks, especially on curves or downhill sections.

In rain, fog, or snow, speed must be lowered significantly, especially on highways, to maintain traction and control.

Spanish law limits trucks to 80 km/h while overtaking on secondary roads to ensure safety.

Heavy trucks often face entry bans during peak hours, especially for pollution or congestion control.

Longer Heavier Trucks (LHTs) are subject to strict routing and must adhere to reduced speed and safety conditions.

In Spain, campaigns highlight that crash fatality risk rises exponentially with speed, especially for heavy trucks.

Truck access in logistics areas is regulated; typical limits are 20 to 30 km/h to protect workers and pedestrians.

On conventional single carriageway roads, the maximum truck speed is 80 km/h.

Truck drivers must slow down at intersections, especially unmarked or with poor visibility.

In school zones, truck speed must be reduced to 20 to 30 km/h or as indicated by signs or road markings.

Due to space limits and rollover risk, trucks must take roundabouts slowly, often under 30 km/h.

Trucks must maintain a minimum 50 meters behind other vehicles unless overtaking.

Adaptive cruise should not exceed truck-specific limits, and must detect vehicles in blind spots.

In adverse traction conditions, trucks must slow drastically, using chains or winter tires where required.

Trucks may be prohibited from using certain left-hand lanes, especially during traffic control measures.

Speed should be 5 to 10 km/h, and hazard lights activated when maneuvering in tight or pedestrian-heavy spaces.
