Potential risks 

Risk of accident 

Caused by the vehicle starting off by itself during the starting procedure (e.g. during compression test) due to engaged gear  or with the engine running and vehicles with automatic transmission due to selector lever position "P" or 

"N"  not being engaged (except for vehicles that do not have selector lever position "P").

Risk of injury 

Severe injuries  can be caused by freely rotating parts in the area of the running engine.

Because the engine heats up when operating, serious burns can be caused by touching unshielded parts.
