The model: Protruding load: divisible or indivisible?

Indivisible load may protrude up to 1 m in front of the car; divisible load nothing (0 cm) in front (Book p.227-229). For both types it also applies: up to 20 cm to the side and up to 1 m at the rear. And a hard ceiling regardless of type: car plus load never higher than 4 m, no wider than 2.55 m, no longer than 12 m.
