21 Speed-limit where a speed-limit sign applies

(1) The speed-limit applying to a driver for a length of road to which a speed-limit sign applies is the number of kilometres per hour indicated by the number on the sign.

(2) However, if the number on the speed-limit sign is over 100 the speed-limit applying to the driver for the length of road is 100 kilometres per hour if the driver is driving—

(a) a bus with a GVM over 5 tonnes; or

(b) a prime mover with a GCM over 22 tonnes; or

(c) a vehicle other than a bus with a GVM over 12 tonnes.

1 Bus, GCM, GVM and prime mover are defined in the Road Safety Act 1986. Vehicle is defined in rule 15.

Note 2 to rule 21(2) amended by S.R. No. 21/2025 rule 5.

2 If the vehicle is a class O vehicle as defined by the Road Safety (Vehicles) Regulations 2021, or a class 1 heavy vehicle, class 2 heavy vehicle or class 3 heavy vehicle as defined by the Heavy Vehicle National Law (Victoria), the vehicle may be restricted to a lower speed-limit by conditions imposed on a permit or notice applying to the vehicle.

(3) A speed-limit sign on a road applies to the length of road beginning at the sign and ending at the nearest of the following—

(a) a speed-limit sign on the road with a different number on the sign;

(b) an end speed-limit sign or a speed derestriction sign on the road;

1 T-intersection is defined in the dictionary.

• Speed-limit signs
• Speed-limit sign (Standard sign) Speed-limit sign (Variable illuminated message sign)
• Other signs
• End speed-limit sign Speed derestriction sign

1 There are other permitted versions of the speed-limit sign—see the diagrams in Schedule 3.

2 A speed-limit sign or an end speed-limit sign may have a different number on the sign—see rule 316(4).

22 Speed-limit in a speed-limited area

(1) The speed-limit applying to a driver for any length of road in a speed-limited area is the number of kilometres per hour indicated by the number on the area speed-limit sign on a road into the area, unless another speed-limit applies to the driver for the length of road under another rule of this Part.
