Cars are environmental objects on the various multiplayer maps and single-player levels in the Call of Duty series. They can either take the form of civilian cars (Call of Duty 4: Modern Warfare and Call of Duty: Modern Warfare 2) or trucks (Call of Duty: World at War). Cars are littered across the maps (usually on the streets) and can easily be destroyed with explosives, light machine guns, etc. When cars sustain enough damage, they will catch on fire. Cars on fire will sustain constant damage until it explodes. This puts the player at great risk whenever they decide to hide behind a vehicle and can cause great frustration, especially if they were killed in either the multiplayer or singleplayer levels due to this.
Not all cars are stationary objects. One exception is the car the player is in, in the Call of Duty 4: Modern Warfare level "The Coup". Another exception is the car seen in the Call of Duty: World at War level "Vendetta", in which General Amsel rides in at the start and at the end when Reznov and Dimitri attempt to kill him. Gary "Roach" Sanderson and Joseph Allen ride in two different cars in Call of Duty:Modern Warfare 2 as well, while several civilian cars driven by Brazilian citizens and gangs in "Takedown". Even in Call of Duty, there was a mission in which the protagonist has to escape a tank by driving a car.
In Multiplayer, the last player to damage the car gets any kills from it. Therefore allies are unaffected by explosions from cars as long as the player shoots them last. Likewise, in hardcore they may incur teamkills for no apparent reason if they leave flaming cars around. Kills by cars do not count towards the Danger Close Pro challenges.
Here is a list of Multiplayer levels containing destroyable cars.
On the level "Exodus", right at the start, if the player goes to the opposite side of Honey Badger and stays on the pavement they will see a civilian driving a red car come up the street and crash into some barriers blocking the road. The car will blow up, and if the player looks inside the exploded car, there will be no remains.
Cars instantly explode if the player jump onto them from far up.
Most vehicles in Call of Duty: Modern Warfare 2 have Infinity Ward references on their license plates.
In Call of Duty: Black Ops, the player can fly an Mi-24 Hind in the mission "Payback": the first player-controlled helicopter in single-player.
Checker Sedans are featured on many levels in Call Of Duty: Black Ops.
In "Operation 40", the player will fight against Cuban police who drive what appear to resemble a crossover between a 1957 Chevrolet and a 1957 Ford.
In "Vorkuta", at the end of the mission, the player will drive a motorcycle to get to the train.
