Construction Traffic Control Procedure for Project Sites

Below is a standard HSE procedure that describes the general traffic rules for construction site operations.

This safety instruction is the minimum standard that is to be adopted on construction project sites for construction traffic control.

Client requirements on specific projects may reflect a higher standard to be complied with by the responsible personnel on that projects.

Overall the project head and relevant discipline Incharge are having responsibilities for the implementation of this standard safety procedure.

Authority to Operate

No person should operate any vehicle on the project site unless:

i. The person is the holder of a current driver’s license or current International license of the appropriate class. Expatriates should obtain a local driver’s license at the first available opportunity;

ii. He/she has satisfied the Project Manager that he/she is familiar with the traffic rules and regulations contained in this policy and passed a written examination.

iii. The person has been issued with a driving permit which specifies the particular type of equipment he/she is authorised to operate and the particular areas in which he/she may operate that equipment.

Speed Limits

a) Construction Roads: All Vehicles – 15 km/h maximum, or as posted on the site.

b) Whilst no vehicle may be driven at a speed in excess of that stated above, all drivers will drive at safe speeds according to conditions existing at the particular time and place.

c) Conditions such as fog, dust, rain, slippery roads etc., must be taken into account and speeds should be reduced accordingly.

d) There may be other situations for example in the workshop areas where reduced speed limits apply.

e) Traffic signs will designate these reduced speed limits.

f) Caution is required for areas where personnel, animals and wildlife are present.

Vehicle Movement

A person should not enter or remain at a construction site if he/she is:

i. Under the influence of alcohol or a drug; or

ii. Suffering from any physical or mental condition, to the extent that he is thereby prevented from performing his duties in a safe manner.

iii. A driver should keep his vehicle as close as practicable to the correct side of any road or ramp. (right or left depending on country’s rules).

iv. Under unusual conditions special traffic arrangements may be made at the discretion of the Project Manager or an official appointed by him.

v. A driver should not under any circumstances enter any area displaying a “Closed” sign.

vi. The driver should ensure the vehicle is in a safe working condition before starting the vehicle.

Audible Signals

Operators of vehicles must give the correct horn signal before starting the engine and before moving in any direction.

i. 1 Blasts – Prior to moving forward.

ii. 2 Blasts – Prior to reversing.


a) Light vehicles may overtake other vehicles provided:

i. It is safe to overtake and the speed limit is not exceeded;

ii. There is sufficient visibility to ensure there is no oncoming traffic;

iii. Extra precautions are required when overtaking graders and other slow moving equipment. Signal intentions well in advance before passing;

iv. Water trucks do not have sprays in operation;

v. The vehicles are not approaching any road intersection or junction.

b) Heavy vehicles should not overtake other vehicles except in the following circumstances:Construction Traffic Control Procedure for Project Sites

i. Overtaking a tracked machine;

ii. Overtaking an operating grader or roller;

iii. Overtaking a broken down vehicle. The operator or driver of this vehicle must assist with traffic control for the safe passing of his vehicle.

c) All rubber tyred vehicles, if in a position to be overtaken should pull to the left of the haul road and slow down. This indicates that they may be overtaken.

d) In the above three overtaking exceptions, the operator of the overtaking vehicle is responsible for the safe completion of the manoeuvres.


a) Vehicles making U – turns must obey the following procedure:

i. Pull to the correct side of the road and stop;

ii. Ensure no traffic is following or approaching for a distance of 300 meters;

iii. Indicate your intention by use of the indicators;

iv. Make U – turn only after ensuring the area is clear of vehicles;

b) The onus for safe completion of U – turns always remains with the driver of the vehicle making the U – turn.

Right of Way

Priority of Traffic on Haul Roads

a) Water Trucks

b) Operating Graders

c) Loaded haul trucks

d) Empty haul trucks

e) Other traffic

Exceptions to Above Rules

a) Vehicles entering haul roads will give way to all vehicles proceeding in either direction along the haul road.

b) All vehicles will give way to emergency vehicles displaying a flashing light.

c) The driver of a vehicle having the right of way over another vehicle should not endanger himself or others, through insistence on that right, and should forego his right of way, if necessary, to avoid collision.

Parking and Standing of Vehicles

a) Ideally, safe parking of any vehicle, no matter how big or small requires that, if the park brake is released and the vehicle is out of gear, the vehicle will not move. Before deciding that a parking area is suitable, carry out this test, and if you are satisfied with the area chosen, firmly apply the vehicle park brake and lower all hydraulic attachments to ground before leaving the vehicle.

b) If the ideal parking situation cannot be achieved a “defensive” parking position should be obtained which will minimize the distance of travel of an uncontrolled vehicle. (An example is to turn steering wheel into a Berm)

c) Do not park or stand a vehicle in a position that will endanger other traffic.

d) Do not park closer than 30 meters to the operating area or parked position of any heavy vehicle. Closer parking is only permitted with approval of the operator, which would be in exceptional circumstances, or designated parking areas.

General Guidelines for Construction Traffic Control

a) Seat belts are to be fitted to all vehicles and mobile plant.

b) While driving seat belts must be worn in all vehicles where fitted.

c) No person other than the driver should ride on any vehicle unless the vehicle is fitted with approved seating for passengers.

d) No person should get on or off a moving vehicle.

e) Do not walk immediately in front or behind any heavy vehicle.

f) Do not stand alongside of or behind tipping trucks.

g) If you wish to speak to the driver of a vehicle, do not approach the vehicle until you are certain that the driver has seen you.

h) The driver will signify that you are expected to approach by:

  • Looking directly at you.
  • Bringing the vehicle to a parking position and lowering all hydraulic implements.
  • Where possible, you should contact the operator by radio and inform him of your intentions.

i) Always use a ladder, handrails or steps when leaving or entering any vehicle or machine. Step down, do not jump.

j) Do not reverse any vehicle on an active haul road.

k) Do not drive over any unprotected trailing electric cables, air hoses, water lines, or hoses.

l) All cranes and forklifts must have an amber beacon whilst mobile.

m) All persons must obey all advisory and mandatory traffic signs.

Mechanical Condition of Vehicles

a) Before operating any piece of equipment the operator must perform the pre-start checks that apply to that particular piece of equipment.

b) No vehicle should be operated unless it is fitted with a fully charged fire extinguisher.

c) Do not operate any equipment, which you consider to be in an unsafe condition.

d) Report faults to your foreman for remedial action.

Night Operations

a) Operators must have vehicle headlights illuminated between sunset and sunrise or in conditions where visibility is impaired due to adverse conditions, e.g. Fog, rain or dust.

b) All the operators must dip their headlights when other vehicles are approaching.

c) Operators must ensure all vehicle lights are operational and not obscured by dirt or mud.
