It is important to be alert to motorcycles because:

Motorcycles are smaller and harder to see than cars. Because of their size, they are easily hidden in a car’s blind spot. It may be difficult to judge your distance to a motorcycle and difficult to tell how fast a motorcycle is moving, so always be alert and extra cautious when near a motorcyclist.

• They are more difficult to see than cars.
• They rarely use their headlights.
• Motorcyclists are less skilled drivers than other motorists.
• All of the above.
