The difference between trail and road surface for running is that trail is usually dirt roads as opposed to tarred (tarmac) surfaces associated with road surfaces.
The Apparatus fixed to the wheels of a car to lessen the effects of rough road surfaces??? Answer: steering wheel
Yes, friction depends on the types of surfaces involved due to factors such as smoothness and stickiness. Friction also increases with the force pressing the surfaces together, as more force results in stronger interlocking of the surface features, leading to greater resistance to motion.
The normal transfer case range for a Humvee on hard road surfaces is typically 2-wheel drive (2H) or 4-wheel drive (4H). 2H is suitable for regular driving conditions, while 4H is ideal for off-road or low-traction surfaces. It's important to avoid using 4-wheel drive on hard road surfaces to prevent damage to the vehicle's drivetrain.
Any solid object has a surface, and there are almost as many types of surfaces as there are classifications of objects. Surfaces can be smooth, granular, abrasive, glossy, flat, curved, and in any shape or texture imaginable.
Yes, some road surfaces are indeed slipperier than others. Surfaces like ice, wet pavement, or loose gravel are more slippery and pose a greater risk of losing traction compared to dry asphalt or concrete surfaces. It is important for drivers to adjust their speed and driving style based on the road surface conditions to maintain control of their vehicle.

This would be essentially impossible; each state has widely varying road surfaces within it, and road surfaces do not necessarily vary from state to state. Whether or not they can, however, is mostly irrelevant since it is much simpler for them to use their GPS which will give them information much more specific than what state they are over.
The force with which both surfaces are touching and the types of surfaces involved
Cold winters can damage road surfaces by causing freeze-thaw cycles, where water seeps into cracks in the pavement, freezes and expands, and then thaws, leading to the formation of potholes and cracks. Additionally, the use of de-icing salts can accelerate deterioration of road surfaces by increasing the rate of corrosion on the pavement.
Dry asphalt roads
New road surfaces are typically developed and tested by civil engineers, pavement scientists, and transportation researchers. These professionals work collaboratively with government agencies, contractors, and industry partners to innovate and implement new road construction materials and technologies.
