Crossing the solid white edge line is permitted in which situation?

• A. Only during an emergency
• B. Never
• C. Only when passing another vehicle
• D. Anytime you want

Answer: (A)

Crossing a solid white edge line is allowed only in an emergency. The solid edge line marks the boundary between the paved roadway and the shoulder, which is not a travel lane. Driving on or across the shoulder is unsafe and only justified when you must avoid a collision or when you need to pull off the road to deal with an emergency or reach a safe place. Daily driving or using the shoulder for convenience isn’t permitted, which is why options suggesting passing another vehicle or driving whenever you want aren’t correct. The option stating never allows for emergencies where using the shoulder is necessary, so the emergency scenario is the correct context.
