The National Car Test (NCT) is a mandatory vehicle inspection program in Ireland. Its primary goal is to ensure road safety and environmental protection by enforcing the roadworthiness of cars in the country. Introduced in 2000, the NCT is managed by the National Car Testing Service and is required for cars that are four years old or more. The test checks various components of the vehicle, including brakes, exhaust system, lights, and tire condition. Failing to comply with NCT requirements can result in penalties, including fines and points on the driver’s license. Regular updates and rigorous checks ensure that the NCT adapts to new safety standards and technological advancements, reinforcing its essential role in maintaining road safety in Ireland.
