Texas DMV Written Driving Practice Test

What should you always do when entering a roundabout?

1. Keep to the right of the circle opening

2. Stop and wait

3. Look to the left before entering

4. Go straight and exit allowing the following vehicle to enter first

The correct answer is: Look to the left before entering

When entering a roundabout, it is important to always look to the left before entering. This is because traffic in a roundabout flows counterclockwise, and you need to ensure that there is no oncoming traffic from the left before entering. Option A, keeping to the right of the circle opening, is incorrect as it is the default direction of travel in a roundabout and it does not address the need to check for oncoming traffic. Option B, stopping and waiting, is incorrect as it goes against the general flow of a roundabout and can cause confusion for other drivers. Option D, going straight and exiting allowing the following vehicle to enter first, is incorrect as it is also not in accordance with the overall flow of a roundabout and can potentially cause a traffic jam. Therefore, the correct answer is C, to look to the left before entering.
