What is the maximum speed limit for a truck driver with a maximum weight of not more than 3.5 tons in the area affected by the signs?

توضیح

The truck silhouette on the supplementary plate restricts the 50 km/h limit to goods vehicles whose permissible maximum mass exceeds 3.5 tonnes. A truck at or below 3.5 tonnes is outside that class, so beyond a built-up area it keeps the ordinary 90 km/h ceiling.
