What is a curve of the road
A curve is a section of the road that bends or turns instead of going straight. You’ll commonly see curves on highways, mountain roads, and rural areas.
✅ What to DO in a Curve?
3 things
✅ What to DO in a Curve:
✔️ Slow down BEFORE the curve – Reduce speed before entering.
✔️ Ease off the gas, don’t brake hard – Let the car naturally slow down.
✔️ Steer smoothly through the curve – Gradual steering keeps the car stable.
What 3 things to avoid?
Avoid:
1. go too fast
2. brake too hard
3. turn too sharply
Why curves are tricky?
Why Curves Are Tricky?
Going too fast can make you lose control or skid.
Braking too hard in a curve can cause your car to slide.
Turning too sharply can make the car unstable.
What are 3 types of curves?
3 Types of Curves:
🔄 Gentle Curve – A slight bend in the road (easier to navigate).
🌀 Sharp Curve – A tighter turn that requires slowing down.
⚠️ Hairpin Turn – A very sharp, almost U-shaped turn (common on mountain roads).
What are 3 things to do if you enter the curve too fast?
If you enter a curve too fast, the best thing to do is:
✔️ Grip the steering wheel firmly to stay in control.
✔️ Ease off the gas to naturally slow down without skidding.
✔️ Steer smoothly through the curve—no sudden movements!
🚫 Why NOT the other options?
❌ A) Slam on the brakes – This can cause the car to skid.
❌ C) Turn the wheel sharply – This may cause oversteering and loss of control.
❌ D) Speed up – This makes the situation worse, increasing the risk of sliding off the road.
What are interstates with three-digit?
e.g. i-405, i-110
Three-Digit Interstates (Auxiliary Routes)
These are connected to a main interstate and serve specific areas:
1. Even first digit (e.g., I-405, I-275) → These are bypass or beltway routes around a city.
2. Odd first digit (e.g., I-110, I-395) → These are spur routes that lead into a city center.
For example:
* I-285 in Atlanta is a loop (bypass) around the city.
* I-110 in Los Angeles is a spur connecting downtown to I-10.
If an interstate has three-digit and the first digit is an even number, what kind of route is this?

What do odd and even numbers mean for Main Interstate Highways?
Main Interstate Highways:
1. North-South Interstates → Odd numbers
* Example: I-5, I-35, I-95 (Run from south to north)
* Lower numbers are in the West (I-5 in California), and higher numbers are in the East (I-95 along the East Coast).
2. East-West Interstates → Even numbers
* Example: I-10, I-40, I-90 (Run from west to east)
* Lower numbers are in the South (I-10 along the Gulf Coast), and higher numbers are in the North (I-90 near the U.S.-Canada border).
How many digits do main interstate highways usually have?
Main interstate highways usually have one or two digits (e.g., I-5, I-10, I-95), while three-digit interstates (I-405, I-285, I-110) are auxiliary routes connected to a main interstate.
Main Interstate Highways (1- or 2-digit numbers)
* These are the primary cross-country highways.
* Odd numbers (I-5, I-35, I-95) → Run north-south.
* Even numbers (I-10, I-40, I-90) → Run east-west.
* Lower numbers are in the west and south, higher numbers are in the east and north.
What directions of highways tend to have higher number?
What directions tend to have lower number?
- Lower numbers are in the west and south, higher numbers are in the east and north.
