What two hazards are associated with electric vehicles?

The correct answer identifies two significant hazards associated with electric vehicles: the high voltage battery and unexpected movement.

Electric vehicles are powered by high voltage batteries, which can present serious risks such as electrical shock or fire if damaged or improperly handled. These batteries store a substantial amount of energy; therefore, safety protocols must be observed to prevent accidents during repairs or in the event of a collision.

Unexpected movement is also a critical hazard. Electric vehicles can start or move without warning, particularly when they are in a silent mode or when a driver inadvertently engages the accelerator. This can pose risks to anyone in the vicinity, including emergency responders and pedestrians, making awareness of vehicle behavior critical in safety protocols.

The other choices lack relevance to the primary hazards related to electric vehicle operations and maintenance. Large amounts of fuel are not applicable, as electric vehicles do not rely on traditional fuels, and elements like power steering or electric seat controls, while they may involve electrical systems, do not carry the same level of inherent danger associated with electric vehicles' unique characteristics.
