Saudi Arabia Heavy Truck Speed Limiter Regulations: Complete HGV Guide

Saudi Arabia has one of the most active heavy truck sectors in the Middle East. Thousands of HGVs traverse the Kingdom daily, carrying freight between its major cities, industrial zones, ports, and border crossings. Heavy truck speed limiter regulations are rigorously enforced by the Transport General Authority (TGA) and Muroor (traffic police), with specific limits depending on vehicle type and gross vehicle weight.

This guide covers everything heavy truck operators need to know about speed limiter compliance in Saudi Arabia.

Speed Limits by Heavy Vehicle Category

Saudi Arabia applies different speed limiter settings based on vehicle type and intended use. Understanding which limit applies to your vehicles is the essential first step in compliance.

Rigid Heavy Goods Vehicles (Over 3.5 Tonnes GVW)

Rigid trucks over 3.5 tonnes gross vehicle weight must be fitted with speed limiters set to a maximum of 100 km/h. This applies to:

• Distribution trucks
• Flatbed vehicles
• Box body trucks
• Refrigerated trucks
• Crane trucks
• Recovery vehicles

Articulated Vehicles and Road Trains

Articulated trucks (tractor units with semi-trailers) and multi-trailer combinations must be speed-limited to 90 km/h. This lower limit reflects the increased stopping distances and stability considerations of longer, heavier vehicle combinations.

This category includes:

• Standard tractor-trailer combinations
• Double-trailer configurations
• Low-loader combinations carrying heavy plant or equipment
• Car transporters

Tanker Vehicles

Vehicles carrying hazardous materials, fuel, chemicals, or liquefied gases are subject to a speed limit of 80 km/h. The lower limit accounts for the additional risk associated with dangerous goods transport, including:

• Fuel tankers
• Chemical tankers
• LPG and LNG carriers
• Water tankers operating on public roads (when classified as heavy vehicles)

Construction and Specialist Heavy Vehicles

Heavy construction vehicles operating on public roads — such as concrete mixers, tipper trucks moving between quarries and construction sites, and heavy plant transporters — are typically limited to 80 km/h.

Vehicles operating exclusively within closed construction sites are governed by site-specific rules rather than national road regulations, but many contractors apply speed limiters regardless to meet client HSE requirements.

TGA (Transport General Authority) Enforcement

The TGA is the primary regulatory body for commercial transport in Saudi Arabia. Operating under the Ministry of Transport and Logistic Services, the TGA’s enforcement activities include:

Operating Licence Requirements

Fleet operators must hold a valid TGA licence to operate heavy vehicles commercially in Saudi Arabia. Speed limiter compliance is a condition of this licence. Operators must demonstrate:

• All applicable vehicles have certified speed limiters installed
• Devices are set to the correct limit for each vehicle category
• Records of installation, testing, and maintenance are maintained
• A fleet management process ensures ongoing compliance

Wayside Checks and Inspections

The TGA operates weigh stations and inspection points on major highways. Heavy vehicles are subject to random checks that include:

• Speed limiter presence and functionality
• Speed limiter certificate validity
• Tachograph or IVMS data showing compliance with speed limits
• Overall vehicle roadworthiness

Fahas Vehicle Inspection

The periodic vehicle inspection (Fahas) is mandatory for all vehicles in Saudi Arabia. For heavy trucks, the inspection includes specific checks on:

• Speed limiter installation and condition
• Correct speed limit setting for the vehicle category
• Tamper seal integrity
• Speed limiter certificate documentation

Vehicles that fail the speed limiter component of the Fahas inspection cannot be re-registered until the issue is resolved.

Common Compliance Challenges for Heavy Truck Operators

Mixed Fleet Categories

Many fleet operators run vehicles across multiple categories — rigid trucks, articulated vehicles, and tankers — each requiring different speed limiter settings. Managing compliance across a mixed fleet requires careful tracking of which vehicles need which settings.

AutoKontrol’s System 80 speed limiter can be calibrated to any required speed setting, and our technical documentation clearly identifies the correct setting for each vehicle category. For fleet managers, we recommend maintaining a compliance register that maps each vehicle to its correct speed limit and certification status.

Extreme Operating Conditions

Saudi Arabia’s climate presents genuine engineering challenges for speed limiter devices. Ambient temperatures regularly exceed 50 degrees Celsius, and engine bay temperatures can be significantly higher. Dust, sand, and vibration add further stress.

The System 80 is designed and tested for continuous operation in extreme conditions. Its solid-state electronics contain no moving parts, and the drive-by-wire interface connects directly to the vehicle’s existing electronic throttle system without introducing additional mechanical components that could fail.

Long-Distance Operations

Heavy trucks in Saudi Arabia routinely cover distances of 1,000 kilometres or more in a single journey — Riyadh to Jeddah is approximately 950 km, Dammam to the Jordanian border over 1,300 km. The speed limiter must operate reliably for extended periods without drift or malfunction.

The System 80’s ECE R89 type approval includes endurance testing that verifies consistent speed limitation over prolonged operation. The device maintains its set speed accurately regardless of driving duration, gradient, or engine load.

Vehicle Age and Compatibility

Saudi Arabia’s heavy truck fleet includes a wide range of vehicle ages and makes. While newer vehicles often have factory-fitted speed limiters, older vehicles and those imported from markets without speed limiter requirements need aftermarket devices.

AutoKontrol’s System 80 is compatible with all major commercial vehicle makes operating in the Saudi market, including:

• Mercedes-Benz (Actros, Atego, Arocs)
• MAN (TGS, TGX, TGM)
• Volvo (FH, FM, FMX)
• Scania (R-series, G-series, P-series)
• DAF (XF, CF, LF)
• Renault Trucks (T, D, C, K series)
• Isuzu (N-series, F-series)
• Hino (500, 700 series)
• FUSO (Fighter, Super Great)
• Chinese makes (Sinotruk, Shacman, FAW, Foton)

The last category is particularly relevant as Chinese-manufactured trucks represent a growing share of the Saudi heavy vehicle fleet.

AutoKontrol Products for Saudi Heavy Trucks

System 80

The proven drive-by-wire speed limiter for heavy truck applications. ECE R89 type approved, calibrated to the required Saudi speed limit for your vehicle category. Smooth, progressive speed limitation that heavy vehicle drivers can work with rather than fight against.

TrackSpeed

For operators requiring combined speed limitation and GPS tracking. Particularly relevant for long-distance operations where fleet visibility and journey management are essential, and for contractors meeting client HSE requirements.

SENT Speed Limiter

For newer trucks equipped with SENT-compatible accelerator pedal sensors. The SENT protocol provides direct digital communication between the speed limiter and the throttle system, delivering the highest precision speed limitation available.
