ROCKVILLE, Md. - Police in the U.S. pulled over a motorist dressed as Batman, but the caped crusader escaped -- legally -- without a ticket.

Authorities pulled over the driver of a black Lamborghini with Batman logo tags last week outside Washington. The driver was dressed as the Dark Knight -- cape, mask and all. Police weren't impressed and wanted to talk to him about his superhero logo licence plate, which isn't an approved plate in Maryland.

The driver, who goes by Lenny B. Robinson when not dressed as a superhero to visit sick children at hospitals, was able to show them a proper licence plate.

A video of the stop shows police officers shaking his hand and taking pictures of him with his ride.
