I was in a vehicle accident on March 30. A accident that could have been avoided if the horn on the IS350 2021 was louder. The vehicle that collided into my vehicle was a Dodge Ram that was hauling a travel trailer which was what hit me. I tried honking various times to let the driver know that I was present and that they were merging onto my lane and I believe due to the weak sound of the horns installed in these vehicles the driver of the other car did not hear my warnings and collided into me.
