The MOT and Driving Law Changes Coming into Force in 2019

As vehicle technology and road systems evolve, driving laws and MOT requirements are updated to reflect new safety standards. Several changes were introduced in 2019 that affected how vehicles are tested, how motorists use motorways and how drivers interact with cyclists and road regulations.

Below is a clear breakdown of the key updates.

Updated MOT Rules

New MOT defect categories were introduced to make results clearer and more consistent:

  • Dangerous — Direct risk to road safety or the environment. Fail.
  • Major — Could affect safety or the environment. Fail.
  • Minor — No immediate safety impact but should be repaired soon.
  • Advisory — Potential future issue.
  • Pass — Meets legal standards.

Additional items were added to the MOT test for the first time, including:

  • Under‑inflated tyres
  • Contaminated brake fluid
  • Brake pad warning lights and missing pads/discs
  • Reverse lights (vehicles newer than September 2009)
  • Daytime running lights (vehicles newer than March 2018)

With MOT standards tightening that year, our guide to what MOT advisories really mean helps drivers understand which issues need attention before new rules catch them out.

 

Motorway Rules for Learner Drivers

Learner drivers were permitted to use motorways for the first time, provided:

  • They are accompanied by an approved instructor
  • The vehicle has dual controls
  • Motorway lessons remain optional, not compulsory

This change aimed to improve driver confidence and safety.

Smart Motorway Enforcement

Drivers using closed lanes marked with a red “X” on smart motorways became subject to:

  • £100 fines
  • Three penalty points

Closed lanes are used to protect motorists and emergency services during incidents. Cameras were upgraded to identify drivers who ignore lane closures.

Passing Cyclists

New guidance reinforced safe passing distances. Drivers could receive a £100 fine if they fail to leave adequate space.

The Highway Code recommends:

  • At least 1.5 metres (4.9ft) when passing cyclists at typical speeds

This aims to reduce collisions and improve safety for vulnerable road users.

Diesel Car Tax Changes

From April 2019, Vehicle Excise Duty (VED) for diesel cars was adjusted based on emissions:

  • Higher first‑year rates for vehicles emitting 191–225g/km CO₂ (up to £500 increase)
  • Smaller increases for cleaner vehicles emitting 111–130g/km CO₂ (around £40 increase)

The change encouraged the adoption of lower‑emission vehicles.
