Video updated, with subtitles:

Why would a lorry driver swerve toward people along the side of the road?

Migrants have been attacking, robbing and hijacking trucks along the road to Calais, the purpose to get aboard to reach Britain.

So in this video you can see how migrants are blocking the road and throwing things at the trucks.

Truck drivers and their union have been complaining to the government but apparently have not gotten sufficient protection. This video at least appears to have police in it at the end.
