The comparison is to "Western Europe"
US Embassy - Rome:
TRAFFIC SAFETY AND ROAD CONDITIONS: While in Italy, you may encounter road conditions that differ significantly from those in the United States. Italy has one of the highest rates of car accident deaths in the European Union. ..... Motor scooters are very popular, and scooter drivers often see themselves as exempt from conventions that apply to automobiles. ...... Drivers of bicycles, motorcycles, and other vehicles routinely ignore traffic signals and traffic flows, and park and drive on sidewalks.
Traffic lights are limited and often disobeyed, and a different convention of right-of-way is observed. .... In rural areas, a wide range of speed on highways makes for hazardous driving. Roads are generally narrow and often have no guardrails. Travelers in northern Italy, especially in winter, should be aware of fog and poor visibility, responsible for multiple-car accidents each year.
US Embassy - Paris:
.. but traffic engineering and driving habits pose special dangers. Lane markings and sign placements may not be clear. Drivers should be prepared to make last-minute maneuvers, as most French drivers do. The French typically drive more aggressively and faster than Americans and tend to exceed posted speed limits. Right-of-way rules in France may differ from those in the United States.
Pedestrians make up 13 percent of the deaths in motor vehicle accidents in France (roughly the same as in the United States), but this percentage is increasing. Most of these accidents occur when a pedestrian steps out onto the street, often when a car or motorcycle is making a turn onto a pedestrian crosswalk. Pedestrians should be cautious even when they have a green walking signal since this is no guarantee against aggressive drivers.
US Embassy - Madrid:
Traffic in Madrid and Barcelona is faster paced than in U.S. cities and can be unnerving because of unfamiliar signs or motorbikes weaving between traffic lanes. Drivers should always obey the closest traffic light, as there are separate pedestrian lights in the cities. Drivers should be alert when driving at night in urban areas because of the possibility of encountering drivers or pedestrians under the influence of alcohol.
