When is it permissible to drive off the paved roadway to pass another vehicle?

Answer: B — Under no circumstances

Driving off the paved roadway to pass another vehicle is not permissible under any circumstances. This rule is rooted in safety considerations, as driving on the shoulder can put both the driver and other road users at risk. The shoulder is typically not designed for vehicle traffic and may have obstacles, debris, or a different surface type that could lead to loss of control or accidents. Furthermore, this action can create unpredictable situations for other drivers who may not expect a vehicle to come from the shoulder area. Road safety laws prioritize maintaining the integrity of driving practices on designated road surfaces to ensure the safety of all road users.
