Auto Accidents Car accidents, injuries and fatalities are all on the rise. Until people learn to put down their phones and keep their eyes on the road, distracted driving will continue to take a tragic toll on California drivers.

Motorcycle Accidents – Motorcycles make up three percent of the total vehicle registrations in California, yet bikers account for 17% of all traffic fatalities in the state. California has more motorcycles on the road by far than any other state in the nation. It’s time for California drivers to start looking out for motorcycles and recognize the need to share the road with bikers carefully and respectfully.

Truck Accidents – Truckers and trucking companies routinely flout federal safety regulations designed to prevent serious and deadly truck accidents. Truck drivers stay on the road far longer than is safe and risk drowsy driving fatigue or falling asleep at the wheel. Trucking companies fail to maintain their fleets in safe condition, with thousands of trucks on the road riding on bad tires and bad brakes.

Bicycle Accidents – Cycling is immensely popular in San Francisco, and bicycles are ubiquitous on city streets. Just as cyclists need to obey the rules of the road and ride with due care, drivers must share the road with cyclists and give them the space they need to ride safely. Right-hand turns into the path of a bicycle, crowding a cyclist off the road, and getting “doored” are just a handful of the dangers bicycle riders face every day.

Boat Accidents – California ranks second in the nation for having the highest number of boats, and boating accidents, injuries and deaths. As a recreational activity, less concern is given to speeding, drinking and reckless operation of a boat than to motor vehicles on the road, but the results can be just as disastrous or worse to other boaters, swimmers, jet skiers and water skiers, and passengers on a negligently driven boat.


Slip and Fall/Premises Liability – California property owners owe a duty to their customers, guests and the general public to maintain their premises in a reasonably safe condition. This includes making periodic inspections of the property and promptly fixing any known hazards or putting up a warning about the danger. William E. Weiss holds negligent property owners accountable when their failures result in a serious slip and fall, trip and fall or other premises liability injury.

Burn Injuries – Burn injuries can be painful, debilitating, permanent and life-threatening. The physical, emotional and psychological toll of burn injuries place them among the most catastrophic injuries a person can suffer. Personal injury attorney William Weiss understands the need of a burn victim for intensive and extensive medical care, rehabilitation, surgeries and other ongoing treatment.

Fracture/Joint Injury – With decades of experience handling cases involving fractures and joint injuries, attorney William Weiss appreciates the many different ways these injuries can occur, the complications that can set in, and the need for the right type and amount of medical treatment and therapy for proper, maximum healing. The law office of William E. Weiss works to obtain a full and fair amount of compensation to deal with these serious injuries.

Traumatic Brain Injury – A TBI can affect cognitive functioning, memory, attention, mood, personality, vision, hearing, motor function, balance, coordination and a host of other areas which can impact one’s ability to work, sleep, get through the day and enjoy a reasonable quality of life. We work with medical experts as necessary to see that our clients get appropriate medical care, rehabilitation and therapy to achieve maximum recovery from their injury.


Motorcycle riders are constantly being profiled, stopped and searched solely on the basis of the fact that they are riding a motorcycle, wearing colors or cuts, or riding or congregating together with other members of a motorcycle club. These actions are in violation of an individual’s constitutional rights to free speech, freedom of association, freedom from unreasonable search and seizure, and freedom from arrest and prosecution without probable cause or a warrant and due process of law. Motorcycle rider rights attorney William Weiss is a strong support of the First Amendment rights of bikers to be free from harassment because of their affiliation with a club or other protected activity. William Weiss is a frequent speaker on motorcycle rider rights in San Francisco, Oakland and surrounding areas. If your rights were violated in a traffic stop or while out in public, you need strong, aggressive representation from a civil rights lawyer who knows your rights and the steps to take to force police and government agencies to stop their unlawful activities, train their personnel properly, and compensate you for the harm done to you.
