Final answer:
Drivers should yield to those already on the public road as part of standard traffic safety guidelines. The safety of crossing a road depends on factors such as the speed of vehicles and pedestrian reaction time, and the color of a vehicle has no impact on its speed.
Step-by-step explanation:
Yes, drivers should yield to drivers already on the public road. This rule is part of basic traffic guidelines that ensure the safety of all road users. When vehicles are entering a roadway from a private road, driveway, or another junction, they are required to yield the right-of-way to vehicles already traveling on the public road.
The question of whether it is safe for a rabbit to cross all 3 lanes of the freeway even when a car is traveling in the furthest lane depends on various factors including the speed of the vehicles and the ability of the rabbit to measure and react quickly to oncoming traffic. Similarly, assessing whether it is safe to walk across the road with a car approaching at 28 m away depends on the vehicle's speed and the pedestrian's walking speed.
Questions such as Do cars travel at the correct speed limit?, Is is safe to cross the road outside of a pedestrian crossing?, and Does the colour of your car determine the speed you are traveling at? relate to overall road and pedestrian safety. The color of a car does not determine its speed; instead, adherence to speed limits and road signs is what contributes to safe driving practices.
