Regolazione della velocità

Speed must be regulated so as not to hinder traffic or cause disorder and, above all, so as not to create a danger to the safety of people and property (not only those being transported) and in any case always within the maximum permitted limits. A correct speed must always be maintained to ensure control of the vehicle and the ability to bring it to a stop within the field of visibility and under safe conditions in the event of unforeseen circumstances. An appropriate speed must be maintained: - according to one's own psychophysical condition - in relation to the characteristics and condition of the vehicle - in relation to the vehicle's load - in relation to atmospheric conditions - in relation to the characteristics and conditions of the road, as well as its state of maintenance and cleanliness (presence of potholes, uneven surfaces, wet foliage) - in relation to traffic conditions It is not true that speed must be regulated based on the time available, the speed of following vehicles (instead, those ahead must be taken into account), engine fuel/power, type of gearbox, driving skill, tyre brand, or the distance to the destination. It is necessary/mandatory to regulate (reduce, moderate) the speed: - on stretches of road where visibility is limited, e.g., near bends, crests, or in the presence of fog or haze - near an intersection or when passing other vehicles proves difficult - in the event of strong crosswinds - when the road is covered by water, snow, ice, leaves, or mud - in case of dazzle caused by the sun - during nighttime hours - on steep descents - in congested passages and narrow points - when traversing built-up areas and on stretches of road lined by buildings - near schools and places frequented by children - in the absence of pavements when pedestrians occupy the carriageway - when encountering a stationary vehicle sign (warning triangle) on the road - in the presence of roadworks - in the case of mixed traffic (presence of slow and fast vehicles or animals and pedestrians occupying the road) It is not true that it is necessary to reduce speed on one-way streets, two-way streets, outside built-up areas, on provincial roads, on uphill roads, in the presence of any road sign, near speed cameras, only in the presence of traffic police officers, or when followed by a scheduled bus. It is mandatory to reduce speed and, where necessary, stop: - when passing other vehicles proves difficult - near pedestrian crossings - when pedestrians on the route are slow to move aside or show signs of uncertainty - when animals on the road show signs of fear - when dazzled - at intersections, to allow vehicles with the right of way to pass, or to verify that others respect our potential right of way It is not true that this is necessary at driveway entrances or near bus stops. If an intersection is crossed at high speed while having the right of way, in the event of an accident, contributory negligence cannot be ruled out. When travelling in parallel files (e.g., along channelised lanes/when traffic is channelised), it is possible to travel in the right lane at a higher speed than in the left lane.
