An apparatus for measuring a closing velocity of a vehicle door includes a housing, first and second sensors, and a processor. The first sensor is coupled to the housing, has a first detection field, and is configured to generate a first signal when the vehicle door passes through the first detection field. The second sensor is coupled to the housing, has a second detection field, and is configured to generate a second signal when the vehicle door passes through the second detection field. The processor is in operable communication with the first and second sensors and is configured to receive the first and second signals and measure a time period between the receiving of the first and second signals.
