In what specific part of the carriageway must vehicles travel?
Traffic rules
Explanation
Vehicles must drive **as close as possible to the right edge** of the roadway. This is important to maintain safety and order on the road, especially in situations of **curves and changes in gradient** where visibility is reduced. By driving on the right, the part of the roadway intended for the opposite direction is left free, avoiding possible collisions.
On roads with **two carriageways**, vehicles must use the carriageway on their right. This ensures that each direction of travel has its own space, reducing the risk of accidents.
Additionally, on roads with **refuges or traffic islands**, you must drive on the right side of these elements, unless the road is one-way, in which case you can drive on either side.
Finally, cars must not drive on the **hard shoulder**, except in cases of emergency or unforeseen circumstances. The hard shoulder is intended for certain slower or special vehicles, such as bicycles or mopeds, which must use it when there is no specific lane for them.
By following these rules, safer and smoother traffic flow is ensured for all road users.
