How can you reduce the noise generated by your motor vehicle?

Your answer is correct because both driving at a low engine speed and using tires with low rolling noise are effective ways to reduce the noise produced by a motor vehicle. According to German traffic rules, keeping the engine RPM low lowers engine and exhaust noise, while tires designed for low rolling resistance also produce less noise when in contact with the road. Removing the air filter insert, however, can increase engine noise and is neither legal nor recommended, as it can also harm the engine and increase emissions. Therefore, focusing on smooth driving and proper equipment helps minimize traffic noise.
