excellent driver; model driver; driver with a clean record
Often refers specifically to a driver who has maintained an accident-free and violation-free record for at least five years, qualifying for preferential treatment such as a shorter license renewal process and lower fees in Japan.
He is an excellent driver, so his license renewal was easy.
If you become a model driver, the lecture time at renewal becomes shorter.
Compound of 優良 (excellent) and ドライバー (driver), a straightforward modern term.
