Frequently Asked Questions
Are motorcycle accidents more common at intersections?
Yes. Intersections are a frequent crash point for motorcyclists because turning vehicles often fail to see an oncoming or approaching bike in time to stop or yield.
How does road surface affect motorcycle safety?
Motorcycles have far less contact with the pavement than cars do, so gravel, oil, wet pavement, or uneven surfaces can cause a rider to lose control much more easily than a driver would in the same spot.
What protective gear reduces injury for riders?
A DOT-approved helmet, a riding jacket, gloves, and sturdy boots all help reduce the severity of injuries in a fall or collision, though they cannot prevent a crash from happening.
What are the most common causes of motorcycle accidents?
Common factors include drivers failing to spot a motorcycle before turning or changing lanes, speeding, following too closely, and riders or drivers being distracted.
What to Do After a Motorcycle Accident in Altadena, CA
Anyone involved in a motorcycle crash should get checked by a medical provider even if they feel fine at the scene, since injuries like road rash, fractures, or head trauma are not always immediately obvious. It helps to get the names and contact information of any witnesses and to photograph the scene, including vehicle positions and any skid marks, before things are moved. Riders should request a copy of the official report once it's filed and keep records of any medical visits related to the crash. Taking time to rest and follow up with a doctor afterward matters more than returning to normal activity too quickly.
