Answer:
1. Difficult,
2. Judge,
3. Speed,
4. Distance.
Explanation:
This is because, most road users, especially motorcyclist tend to have the habit of speeding fast. Thus when crossing into a two-way road, it can be difficult from inside the car to judge the speed and distance of the incoming road users from either front or back.
Hence, when traveling from a one-way road to turn into a two-way road, you should enter the two-way road to the right of the center line. Be alert for traffic, especially motorcycles, as it is DIFFICULT to JUDGE their SPEED and DISTANCE
