Dual Control Cars for Driving Instructors
Dual controls give the instructor the ability to brake, operate the clutch or control the accelerator from the passenger seat. For any professional driving instructor in the UK, understanding the legal position, mechanical principles and costs involved is essential.
Key Facts About Dual Controls
Effectively Mandatory
Not legally required by law, but virtually every specialist insurer requires them as a condition of cover.
Mechanical Linkage
Connected via rods, cables or hydraulics with no electronic delay. Response is immediate and proportional.
GBP 300 to GBP 700
Total installed cost ranges from GBP 300 for automatic to GBP 700 for manual, including professional fitting.
DVSA Tests Require Them
Dual controls are required for the ADI Part 2 and Part 3 tests, and expected by insurers for trainee licence holders.
Legal Position: Are Dual Controls Mandatory?
Dual controls are not a legal requirement under UK road traffic law. There is no legislation that explicitly states a driving instructor must have dual controls fitted to their vehicle. However, in practical terms, operating without them is virtually impossible.
The DVSA strongly recommends dual controls for all vehicles used in driving instruction. Whilst you could technically deliver lessons without them, doing so would raise serious questions about your duty of care.
More importantly, insurance is the deciding factor. Virtually every specialist driving instructor insurance provider requires dual controls as a condition of cover. Without them, you cannot obtain the tuition-use insurance you need to legally operate. This effectively makes dual controls mandatory even though the law does not explicitly demand them.
The DVSA also requires dual controls for the ADI Part 2 and Part 3 tests. Trainee licence holders (pink badge holders) are similarly expected by insurers to have them fitted.
How Dual Controls Work
Manual Cars
A full manual installation typically includes a dual brake pedal, a dual clutch pedal and optionally a dual accelerator. The brake is the most critical safety control and the one used most frequently during lessons.
- ✓ Dual brake pedal (essential)
- ✓ Dual clutch pedal (essential)
- ✓ Dual accelerator (optional)
- ✓ Immediate mechanical response
Automatic Cars
Automatic vehicles require only a dual brake pedal, making fitting simpler and cheaper. Some kits include an inhibitor switch that prevents the pupil from selecting Drive or Reverse at inappropriate moments.
- ✓ Dual brake pedal only
- ✓ Optional inhibitor switch
- ✓ Simpler and cheaper installation
- ✓ Over 40% of tests now automatic
Important: Dual controls must be fitted by a qualified specialist. Incorrect installation can compromise the braking system or create mechanical failures. Always test thoroughly after fitting.
Choosing and Fitting Dual Controls: Costs and Suppliers
The UK market for dual controls is dominated by a small number of specialist manufacturers. He-Man Dual Controls is the largest and most established manufacturer, with a nationwide network of approved fitters. Arthur Franks is another well-regarded manufacturer with vehicle-specific kits.
Both manufacturers maintain lists of compatible vehicles on their websites. Before purchasing a new instruction car, check that a dual control kit is available for your chosen make and model.
Costs breakdown:
- • Manual kit (brake and clutch): GBP 300 to GBP 500 for parts
- • Automatic kit (brake only): GBP 200 to GBP 350 for parts
- • Professional fitting: GBP 100 to GBP 200, typically two to four hours
- • Total installed (manual): GBP 400 to GBP 700
- • Total installed (automatic): GBP 300 to GBP 550
- • Removal: GBP 50 to GBP 100 when selling the vehicle
Always use an approved fitter recommended by the manufacturer. A certificate of installation is normally provided, which your insurer may request as proof of proper fitting. DIY installation is strongly discouraged and could invalidate your insurance.
Dual controls require minimal ongoing maintenance. Check the pedals regularly for smooth operation and have them inspected during your vehicle's annual service. Dual controls cannot be transferred between different car models, so the cost recurs every time you switch vehicles.
