Near what type of traffic situations should motorcyclists be most alert?

Motorcyclists should be most alert near intersections and parking lots because these areas are common locations for potential hazards and collisions. Intersections are particularly dangerous due to the possibility of vehicles running red lights, failing to yield, or making sudden turns without signaling. These unpredictable movements of other drivers can pose significant risks to motorcyclists, who are often less visible than larger vehicles.

Parking lots also present hazards, as drivers may be moving at low speeds while still being distracted. It's not uncommon for vehicles to suddenly back out or pull forward without checking for approaching motorcycles. The close quarters and frequent stops can increase the likelihood of accidents involving a motorcyclist, as these situations require heightened awareness of both pedestrian and vehicle movements.

Highway speeds can be dangerous as well, but the issues tend to be different, focusing more on high-speed collisions and wind resistance rather than the intricate maneuvers found in intersections and parking lots. Having no other vehicles present reduces the likelihood of accidents, and night riding poses its own challenges but does not specifically increase alertness relating to traffic interactions.
