Continuity: Vera gets onto her bus just after Stan and Jack have put spiders in the cab. She is wearing boots when she discovers the spiders, causing her to run into the back of the lorry. As she does so, it is evident that she is wearing shoes.

Factual error: In the scene where Blakey nearly catches Jack in the turn round Betty's house, Blakey tells them to get moving as they are late. At first they both go through the passenger door of the bus at the back before Stan goes round the front to drive, but the bus drives off too soon for Stan to walk to the front, climb in the cab, start the engine and drive off.

Plot hole: When Olive gets into the motorcycle sidecar to go to hospital to have her baby her weight lifts the motorbikes rear wheel off the ground. Stan solves the problem by riding on the rear off the pillion to keep the wheel on the ground. Stan never intended to go to the hospital until this problem occurred, but he was already holding a crash helmet in his hand from the start off this scene.

Continuity: The same two cars pass the lorry before and after Vera crashes into it.

Continuity: In the last scene, when Stan boards his bus inside the depot, the registration number is "WNO476" but, as soon as he drives out the front entrance, it changes to "VNO857".

Plot hole: When Olive gets in the motorcycle sidecar to go to hospital to have her baby, her weight lifts the bikes rear wheel off the ground.
