This lesson explains the specific legal framework governing truck operations on Spain's high-speed road network. It details the different speed limits for trucks on autovías versus autopistas and the regulations regarding which lanes heavy vehicles are permitted to use. Learners will also understand how to interpret specific highway signage relevant to commercial vehicles and any applicable toll regulations.
This lesson focuses on the critical relationship between speed, following distance, and overall traffic safety on highways. It explains how to calculate a safe following distance based on speed and weather conditions, accounting for a truck's longer stopping distance. The content also teaches strategies for managing speed to adapt smoothly to changing traffic flow, enhancing both safety and fuel efficiency.
This lesson provides a detailed guide to performing safe and legal overtaking maneuvers on the highway. It places strong emphasis on the techniques for thoroughly checking the large blind spots around a truck before initiating a lane change. The content also covers judging the necessary speed differential and distance required to complete the pass and return to the lane safely.
This lesson covers the regulations and best practices regarding the use of rest areas and service stations during long-haul journeys. It reinforces the rules on mandatory rest periods to combat driver fatigue and explains how to plan routes to include necessary stops. The content also provides guidance on safe parking procedures within designated truck areas and using stops to perform quick vehicle safety checks.

For trucks and articulated vehicles with a Maximum Authorised Mass (MAM) exceeding 3,500 kg, the general speed limit on autovías and autopistas in Spain is 90 km/h. For vans and light vehicles, the limit is 120 km/h. It's crucial to always check for variable speed limit signs and specific restrictions for your vehicle category.
Overtaking is only permitted on the left lane, provided it is safe to do so and does not impede traffic flow. Trucks must adhere to specific speed limits and ensure they do not exceed the speed limit of the vehicle they are overtaking. Overtaking is generally prohibited in conditions of reduced visibility or when it might endanger other road users.
Maintaining a safe following distance is critical at high speeds. For trucks, a common guideline is to maintain a distance of at least two seconds from the vehicle ahead. This allows ample time to react and brake safely, especially considering the longer stopping distances required for heavy vehicles. Always increase this distance in adverse weather conditions.
When merging, you must adjust your speed to match the flow of traffic on the highway. Use your turn signal, check your mirrors and blind spots, and accelerate in the acceleration lane to merge smoothly and safely into a gap in traffic. Be prepared to slow down or stop if necessary, but ideally, you should time your merge to avoid disrupting highway traffic.
Both autovías and autopistas are high-speed motorways where trucks can operate. Autopistas are typically toll roads, while autovías are generally toll-free, although some sections may have tolls. The driving rules, including speed limits and lane usage for trucks, are largely the same on both types of roads.
Trucks have significant blind spots, particularly to the sides and rear. Before overtaking, drivers must ensure they can see the vehicle they intend to pass in their mirrors and that the vehicle is not in a blind spot. After overtaking, they must ensure they have sufficient space to move back into the original lane without cutting off the passed vehicle, checking all mirrors and blind spots again.
