A vehicle registration plate, also known as a number plate or license plate or licence plate, is a metal or plastic plate attached to a motor vehicle or trailer for official identification purposes. All countries require registration plates for commercial road vehicles such as cars, trucks, and motorcycles, for hire. Whether they are required for other vehicles, such as bicycles, boats, or tractors, may vary by jurisdiction. The registration identifier is a numeric or alphanumeric ID that uniquely identifies the vehicle or vehicle owner within the issuing region's vehicle register. In some countries, the identifier is unique within the entire country, while in others it is unique within a state or province. Whether the identifier is associated with a vehicle or a person also varies by issuing agency. There are also electronic license plates.

A vehicle registration plate, also known as a number plate, license plate or licence plate, is a metal or plastic plate or plates attached to a motor vehicle or trailer for official identification purposes. The registration identifier is a numeric or alphanumeric code that uniquely identifies the vehicle within the issuing authority's database. In Europe most countries have adopted a format for registration plates that satisfies the requirements in the Vienna Convention on Road Traffic, which states that cross-border vehicles must display a distinguishing code for the country of registration on the rear of the vehicle. This sign may be an oval sticker placed separately from the registration plate, or may be incorporated into the plate. When the distinguishing sign is incorporated into the registration plate, it must also appear on the front plate of the vehicle, and may be supplemented with the flag or emblem of the national state, or the emblem of the regional economic integration organisation to which the country belongs. An example of such format is the common EU format, with the EU flag above the country code issued in EU member states.

Graduated driver licensing systems (GDLS) are designed to provide new drivers of motor vehicles with driving experience and skills gradually over time in low-risk environments. There are typically three steps or stages through which new drivers pass. They begin by acquiring a learner's permit, progress to a restricted, probationary or provisional license, followed by receipt of a full driver's license. Graduated drivers' licensing generally restricts nighttime, expressway, and unsupervised driving during initial stages, but lifts these restrictions with time and further testing of the individual, eventually concluding with the individual attaining a full driver's license.
A driver's permit, learner's permit, learner's license or provisional license is a restricted license that is given to a person who is learning to drive, but has not yet satisfied the prerequisite to obtain a driver's license.

To get a learner's permit, one must typically pass a written permit test, take a basic competency test in the vehicle, or both.
