Why should drivers be especially cautious around motorcycles?

Motorcycles are smaller in size compared to cars, which makes them less visible to other drivers on the road. This reduced visibility can lead to accidents, especially if a driver is not actively looking for smaller vehicles while changing lanes or making turns. Furthermore, motorcycles are also more susceptible to skidding, particularly in adverse weather conditions such as rain or snow, due to their lighter weight and different handling characteristics compared to four-wheeled vehicles. This means that even if a motorcycle is in plain sight, the potential for it to lose control is higher, which calls for additional caution from surrounding drivers to ensure safety on the road.

The other options do address various aspects of motorcycle operation and risk. However, none capture the combination of visibility issues and the increased risk in poor weather that makes option C the most comprehensive and relevant answer for why drivers should be particularly cautious around motorcycles.
