There are traffic lights on both sides of the junction! The trouble is, if they are working the traffic is brought to an utterly unfixable jam 24/7. Not working, the jam is limited to rush hours!
Yes tyredness caused the accident.

The origin is very simple. Fuel. Originally, one could hire a 'plane "wet", i.e. fuel cost included in the hourly rate, or "dry" i.e. no fuel included.
Just like car rentals.
