Legal Commentary & Landmark Judgments: Section 198

Section 198 of the Motor Vehicles Act, 1988 protects public safety and parked vehicles by criminalizing unauthorized interference, tampering with mechanical components, releasing brakes, or setting stationary motor vehicles into motion without lawful authority or reasonable excuse.

  • Unauthorised Physical Interference with Vehicles: Penalizes anyone who, without lawful authority or reasonable excuse, enters or moves any stationary motor vehicle, or tampers with the brake or any part of its mechanical or electrical mechanism.
  • Penal Sanction (Post-2019 Enhancement): Punishable with a fine extending up to ₹1,000 (increased from ₹100 by the 2019 Amendment), creating a statutory deterrent against malicious tampering and unauthorized vehicle meddling.
  • Strict Causation in Resultant Accident Liabilities: Where unauthorized interference releases the handbrake or sets a parked vehicle rolling down an incline causing injury, the meddler is directly liable in tort and crime, alongside the owner's statutory duty to securely park.
Key Landmark Precedents:
  • State of Karnataka v. K. Gopalakrishna, 2005 SCC OnLine Kar 212: The Karnataka High Court held that tampering with stationary vehicles or meddling with vehicular mechanisms on public roads creates severe public hazard, and penal provisions under Section 198 must be strictly enforced by traffic authorities.
  • B. Govindarajulu Chetty v. Governor-General in Council, AIR 1948 Mad 438: The High Court affirmed that individuals who unlawfully interfere with stationary transport vehicles on public roads are liable for resultant damage under principles of proximate tortious causation.
Courtroom Practice & Strategic Litigation Guidance:

When defending an owner in an accident where a stationary parked truck rolled down a slope due to third-party tampering, plead Section 198 and provide CCTV footage or witness testimony proving that the vehicle was parked in gear with handbrakes engaged and was subsequently tampered with, thereby establishing novus actus interveniens to defeat tortious negligence.
