When should you turn off your engine in traffic?
When should you turn off your engine in traffic? Turn off your ignition if you're waiting more than 10 seconds. Contrary to popular belief, restarting your car does not burn more fuel than leaving it idling. In fact, idling for just 10 seconds wastes more gas than restarting the engine. Warm up your engine by driving it, not by idling.
What color car gets hit the most?
Research suggests that black vehicles are involved in accidents much more frequently than other color cars. During the day, black vehicles are associated with about a 12 percent increase in crash risk. At night, you're about 47 percent more likely to get into an accident when you're driving a black car.
