Having crossed the road, a person in a wheelchair cannot get up the curb and onto the pavement. What do you do?

You answered the question correctly. In this situation, safety and assistance are the priority. Stopping your car and switching on the hazard lights warns other drivers that there is a temporary stop for an unusual reason, keeping everyone safe. Getting out of the car to help the person in the wheelchair is the proper way to provide assistance to someone in need. Honking and driving around is not appropriate, because it does not help the person and could create a dangerous situation. In traffic situations like this, always combine warning other drivers with actively offering help when someone has difficulties crossing or using the road.
