At a posted stop sign, which action must be completed before checking left and right?
Bring the vehicle to a complete stop.✓Respuesta correcta
Reduce speed without stopping if the road looks clear.
Sound the horn and continue at walking pace.
Check left and right while rolling through.
Explicación
The vehicle must be brought to a complete halt before the driver checks both directions and decides whether it is safe to proceed. Merely reducing speed leaves the vehicle moving and does not satisfy the stop-sign instruction.
