Md State Police seek info about hit & run
A lot of speed differential in that crash.
As others have mentioned, guess a brake check when the other was closing up fast. Too bad. Take a lot to fold up a 70-72 shovel like that.
Brake checking is STUPID. just move over and let people go on their way. If it was a check, the shovel driver sure showed the SD PU driver. /sarcasm
