Fellow contestant Brian Johnson, of rock group AC/DC, clipped the back of her car at Silverstone, in Northants, sending it spinning out of control.
The London-born R&B star, 25, was treated at the track's medical centre and was said to have been conscious.
She was later taken to University Hospital Coventry and Warwickshire.
The hospital said on Sunday that she would be kept in overnight for observation.
A Sky One spokesman said the collision on Sunday afternoon sent Ms Dynamite's Formula Ford spinning down the track for about 50 metres before it came to a halt.
She may have been travelling at more than 100mph when the accident happened, he said.

"We would not let them take part unless we were satisfied with the level of competence they were at and all the necessary safety measures were in place."
