Answer:
D stands for drive.
Step-by-step explanation:
In automatic transmission vehicles, the letter D represents all forward-moving gears. When the engine is running, and the automatic transmission is activated with D, accelerating the car will make it move forward.
Some vehicles will have a series of numbers after the D. The may be labeled ad D1, D2, D3 in that order. These are manuals setting for the forward gear operations. They help the vehicle navigate different terrain as follows
- D1: Suitable for difficult terrains like sand and mud.
- D2: Best for up climbing or hilly roads
- D3: May also be marked as OD or overdrive. It makes the car move fast hence suitable for when overtaking.
For vehicles with only D, the single D combines all the above functions.
