What must bike riders aged 16 years or older adhere to while riding?

Bike riders aged 16 years or older are required to adhere to all traffic laws applicable to motor vehicle operators because bicycles are considered vehicles within the context of the law. This means that cyclists must follow the same rules as drivers of motor vehicles to ensure their safety and the safety of others on the road. This includes obeying traffic signals, signs, and lane usage, as well as being aware of other traffic participants.

Adhering to these laws helps maintain order on the roads and reduces the risk of accidents, thereby promoting a culture of shared responsibility among all road users. Even though bicycles are different in operation compared to motor vehicles, the legal framework treats them similarly in many respects to improve overall traffic safety.

The other choices suggest limited or no adherence to traffic laws, which does not reflect the legal obligations of cyclists operating on public roads.
