ABS (Anti-Lock Braking System)
ABS or an Anti-Lock Braking System is a piece of safety equipment that prevents the wheels of a vehicle from locking up under emergency, panic, or harsh braking conditions. In case of sudden braking, there is a possibility of an immediate loss of traction between the tires and the road surface.
Acceleration is the rate at which the vehicle speed increases.
An accelerometer is the electromechanical part of the telematics device that tells the position of the vehicle and its rate of change. In other words, it measures acceleration.
Advanced Driver Assistance Systems (ADAS) refers to technologies designed to improve safety for drivers, passengers, and pedestrians. Commonly used ADAS are anti-lock braking systems, parking assist, lane assist, tire pressure monitoring, night vision improvements, blind spot detection, and adaptive cruise control.
Alternative Fuel

Alternative fuels are any materials or substances that can be used as fuel other than traditional fossil fuel. Bio-diesel, bio-alcohol, hydrogen, and chemically stored electricity are all examples of alternative fuel.

An automatic on-board recording device (AOBRD) is an in-vehicle device used to keep driver logs. The most common type of AOBRD is an electronic logging device (ELD). The FMCSA 1988 AOBRD rule first defined AOBRDs with far fewer requirements as an option for drivers who wanted to move away from paper logs. The 2012 ELD mandate replaced the 1988 rule but grandfathered in some existing AOBRDs. Electronic on-board recorders (EOBRs) also qualify as AOBRDs. 

An application-programming interface (API) is a set of programming instructions and standards for accessing a web-based software application or web tool. It allows software applications to connect, communicate, and exchange information or functionality with each other.

Many of our Partner integrations use APIs to allow you to access GPS data inside their software.
