<h1>Legal and contractual risks for deploying retrofitted medium and heavy electric trucks: safety, retrofit, emissions, warranties, and liability</h1> A logistics firm, an EV powertrain manufacturer and a cement producer announced deployment of retrofitted medium/heavy electric trucks for bulk transport. Legal issues include compliance with vehicle safety, retrofit and homologation standards, emissions and battery disposal laws, and roadworthiness certifications for heavy commercial vehicles. Contractual risks arise from fleet procurement, performance warranties, maintenance and indemnities, and liability allocation for accidents or drivetrain failures on challenging routes. Regulatory dependency on charging infrastructure and permits may affect operations and expose parties to regulatory or contractual breach claims. Intellectual property, supply-chain warranties and insurance coverage should be reviewed before wider rollout.
