Hello, last night the following happened! So, my dad => at the wheel (including my mom and I) were in a Citroen C5 on the way to my brother, because it was already 18 o’clock, and therefore quite dark, my father could not see the driveway to the house of my brother (are 2 houses with the same driveway…) The house (my brother) is the second, because now my dad wanted to turn into the first driveway (still NOT a blinker) I told him immediately he should We were about 30km/h fast, when we wanted to turn at the right driveway (HABEN SICHER BLINKT) overtakes us at the moment a small Smart Roadster and crawls fully in front… (cot wing, bumper, steering bar over! > Front left) The Smart then it has thrown 2m further on a stone high, so about 300kg heavy stone from vertical, placed on horizontal and itself on top of it remained seated… (estimate the speed at 60km/h) The Smart -drivers now deny that it was his fault…! Police was suburban… Both cars had to be towed! Well, a question like that; how would you judge this situation? If I forgot to mention anything, please let me know.. mfg + thank you in advance…
