What is a driver of a vehicle carrying oversize freight required to do when due to road conditions he cannot be overtaken by other drivers?

1. A Drive until the nearest parking bay or bus station bay and stop to allow other vehicles to overtake him.
2. B Turn on the four distress winkers, and continue driving on the right of the road way.
3. C Swerve his vehicle as far to the right of the roadway as possible, but avoid pulling into the “hard shoulder” because the vehicle’s weight might cause the “shoulder” to collapse.
4. D Slow down and, if necessary, pull into the “hard shoulder” and even stop, to allow the vehicles behind him to overtake safely.
