Police said a New Hampshire school bus driver allowed her 5-year-old son to sit in the driver's seat with the bus running and the boy put it in reverse, sideswiping cars and crashing into a carport.

Merrimack police said Tiffanie Brown was doing a safety check outside the bus last week at an apartment complex parking lot. Her 8-year-old son was with her.

Capt. Peter Albert tells WMUR-TV Brown instructed the 5-year-old to activate the different lights to check them. But the boy somehow put the bus in reverse. The 8-year-old was hanging onto a door at the time.

No one was hurt, but Brown was arrested Monday and charged with reckless conduct and endangering the welfare of a child. It wasn't immediately known if she had a lawyer.
