A learner asks whether they may stop briefly on a highway (freeway-type road) to check a phone message. The instructor should explain that:

1. Stopping on a high-speed road is prohibited except in an emergency, when the vehicle should be moved as far left as possible and hazard lights used
2. It is fine for under one minute
3. It is allowed if the hazard lights are on, for any reason
4. It is allowed on the right-hand side only
