What is the rule regarding priority for emergency vehicles (police, ambulance, fire) in Ghana?

1. They have priority only when traveling on national motorways.
2. You must yield the right-of-way, pull to the right, and stop if necessary when they sound sirens or flash warning lights.
3. They must obey all standard traffic rules, wait in the queue like every other vehicle, and may not pass a red traffic light.
4. They only have priority during daylight hours.
