What should I do if a rented car breaks down during my trip and I’m unable to continue the journey? I want to understand the immediate steps to take to ensure safety and avoid additional charges. Should I contact the rental provider right away, and do they usually offer roadside assistance or a replacement vehicle? Are there any responsibilities on my part, such as arranging temporary repairs or reporting the issue properly? It would be helpful to know how different rental companies handle such situations and what support I can expect.
