In this case, the injured UK citizen can file a personal injury claim under Turkish law, specifically under the Turkish Code of Obligations (TCO), which governs tort liability. To establish liability, the claimant must prove (1) the existence of damage, (2) an unlawful act or negligence by the defendant, and (3) a causal link between the act and the damage suffered. Since the injury occurred due to an object protruding from the defendant's truck, negligence can likely be argued under Article 49 of the TCO, which imposes liability for unlawful acts causing harm. Additionally, if the truck’s owner is a company, vicarious liability under Article 66 may apply, holding the employer responsible for their employee’s negligence. To secure compensation, the claimant must provide medical reports, police reports, witness statements, and any available footage. If successful, litigation costs may also be recoverable under Article 323 of the Turkish Civil Procedure Code, meaning the defendant may be ordered to pay the claimant’s legal expenses. However, it is advisable for the claimant to seek a Turkish lawyer’s assistance to navigate procedural requirements effectively.
