Traffic lights show green, but traffic beyond the junction is queued so heavily that you would probably have to stop inside the intersection. What does Lesotho law require?

1. Wait before the intersection—you may not enter if you will probably be forced to stop on it and block cross traffic
2. Enter anyway, because a green signal always authorises entry
3. Enter and sound the horn until the queue ahead moves
4. Enter and stop across the crossing so you keep your place in the queue
