A rollover is a renewal of a deposit. Instead of liquidating a deposit on maturity, you can roll it over into a new deposit. The outstanding principal of the old deposit is rolled over with or without the interest outstanding on it.

It occurs when a car's tire hits something  such as a curb or ditch  that shifts the vehicle's weight to one side, causing it to roll before it can regain its balance. Speeding: If you speed around a curve or take a turn too fast, the tires can lose their grip on the road, leading to a vehicle rollover.
