Why is it that when approaching a curve on a highway signs are posted to reduce speed?
This is not related to physics but to the driver's attention when approaching a curve. If the speed is kept the same, it's more difficult to control the vehicle specially if the driver is stressed, drunk, tired or sleepy. The probability of an accident would increase on this situation.
Would a rod being turned by a cog go faster if the cog turning the rod was smaller or bigger?
The speed of the rod is proportional to the number of teeth on the cog and that which is driving the cog. If the driver remains the same then in order for the driver and the cog to mate one typically needs to reduce the number of teeth on the cog when it is made smaller. Thus the ratio of the teeth on the driver to that on the cog is increased as will its speed.
Why does an electromagnetic wave in space never slow down?
In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.In empty space, an electromagnetic wave can only travel at one speed - the speed of light.
When you intend to reduce speed or stop what should you do?
Release accelerator.
What do we mean when you say that motion is relative?
It means the motion you measure for something depends on where you measure from. For example, You are on the sidewalk and measure the speed of a truck and its driver to be 60mph. But if you were in the truck and measured the speed of the driver it would be zero, because now, relative to you, the driver is not moving.
What lanes gives drivers time and space to reduce their speeds?
Deceleration lanes give a driver time and space to reduce their speed.
When another driver travels at erratic speed weaves in and out of lanes and sits in unusual postures these are indications that the driver?
is impaired
A driver must reduce speed and adjust to changing conditions in?
adverse weather
Can you give me some road signs please?
There are: 1. stop 2. speed 3. turn lanes 4. reduce speed 5. rest area ahead 6. speed bumps 7. rumble strips ahead (or in the middle)
If someone is driving behind you and they are honking their horn and flashing their lights at you so you speed up to change lanes and you get a ticket for speeding do you have a viable defense?
Not usually. You could have simply changed lanes. the question said "so you speed up to change lanes"

What we call drivers who drive at erratic speed and weave in and out lanes?
Impaired
In which sport do competitors change lanes after every lap?
Speed Skating
What is the use of a cordless radar detector?
It's used to detect if your speed is being monitored by a radar gun by the police. They are used so the driver can reduce his speed before receiving a ticket.
How does adaptive laser guided cruise control work?
How it works is not nearly as important as what it does. The "how" involves distance sensors similar to radar guns, computers, and algorithms. The "what" that the driver needs to know is that it will slow the car down automatically if the car see's a vehicle in front of it getting too close, and match that cars speed. Typically the car will then speed back up to the speed set by the driver when it no longer sees that obstacle a.k.a. that car exited, sped up, or you changed lanes.

When another driver forces you to speed up slow down or change lanes what is the safe thing to do?
Another driver cannot "force" you to speed up or change lanes without driving very dangerously indeed, in which case note his registration and try to stay safe yourself. Just because someone behind you obviously wants to go faster, you don't have to, especially if you're already near the speed limit. Drive safely and for yourself. If the driver in front slows down and it's not safe to pass, you just have to slow down too. Don't use your horn to start an argument, only to let him know you're there (if you think he may not have seen you).
