Which defects of a vehicle can result in a danger for road traffic?

Your answer is correct because all the listed defects can create hazards in road traffic. Worn tyres reduce grip on the road, especially in wet conditions, increasing the risk of skidding or losing control. Defective rear lamps make it harder for other drivers to see your vehicle and anticipate your actions, especially at night or in poor visibility, leading to potential accidents. Insufficient braking effect means your vehicle cannot stop safely or quickly enough, increasing the chance of collisions. German traffic rules require vehicles to be in a safe and roadworthy condition to protect all road users. Regular maintenance and checks help prevent these dangers.
