Driving test test was introduced in France in 1899. To make the test fair, written driving tests are normally standardized tests, meaning that everyone takes the same test under the same conditions. In many places the test can be done by computer, and typically consists of questions related to road signs and traffic laws of the respective country, but may also include questions related to road safety best practices or technical questions regarding vehicle operation and maintenance. In many countries, passing a written driving test is required to be allowed to sit the practical test. Depending on the country and on the
World Motorcycle Test Cycle can be performed using a finished vehicle (rather than an engine test rig) which can be used repeatedly with the expectation that consistent results will be produced. The driving cycles are intended to represent typical driving conditions. For example, a motorcycle's wheels are placed in contact with a set of rollers which can be adjusted to simulate friction losses and aerodynamic resistance. The motorcycle is then accelerated and braked in a variety of patterns to represent a particular type of real-world operation. Therefore, statistical conclusions on pollutants emitted or fuel consumed by a variety of vehicles and testers (e.g. manufacturers)
