5.28. 1 – Entering and Leaving Expressways

Exit ramps are short, one-way ramps. At the beginning of most exit ramps is a deceleration lane. Make sure you are in the proper lane to leave the highway well in advance of the deceleration lane. Use the deceleration lane and the exit ramp to slow down when leaving the highway.

The speed limit is 25 mph, unless otherwise posted.

1. On the entrance ramp, begin checking for an opening in traffic. Signal for your turn.
2. As the ramp straightens into the acceleration lane, speed up.
3. Merge into traffic when you can do so safely.

Entrance ramp

What is the most important and safest thing a driver can do before driving away? Put on a safety belt and turn off electronics. Illegal in Maryland if the vehicle is unattended and is not necessary. Check all mirrors, complete head checks, and use back up cameras if available.

*Adjust your speed to exit ramp speed and prepare to stop or yield. Remain alert. What are three possible exiting problems?…

• Entrance ramps- choosing wrong ramp, short ramp, high walls blocking view ahead.
• Entrance ramp signal lights-you must wait for the green light to go (these are used to space out traffic)

When exiting an expressway, it is important to be alert to other traffic moving nearby. Be sure to look at the new posted speed limit and check your speedometer. It is unlikely that you will be exiting onto a road with a speed limit as high as the one found on the expressway.

Following these defensive driving tips can help reduce your risk behind the wheel:

• Think safety first.
• Be aware of your surroundings — pay attention.
• Do not depend on other drivers.
• Follow the 3- to 4-second rule.
• Keep your speed down.
• Have an escape route.
• Separate risks.
• Cut out distractions.

Passing is one of the most dangerous maneuvers a driver can attempt. High speed passing on expressways adds to the danger and a high volume of traffic on expressways increases the chances of collisions. This being said, it is still safer to pass on an expressway than a two-lane roadway.

Entering an expressway – expressway entrances include three areas: the entrance ramp, the acceleration lane, and the merge area. The entrance ramp allows the driver time to search the expressway and evaluate speed and available space before entering. Entrance ramps may be uphill, downhill, or level with the expressway.

The WRONG WAY sign may accompany the DO NOT ENTER sign. This rectangular red and white sign is a traffic regulatory sign. If you see one or both of these signs, drive to the side and stop; you are going against traffic.

In good weather, you want a 2-second distance. When driving through fog, you should up the distance to 5 seconds.

You can use the defroster or air conditioner to keep the inside of your vehicle windows clear after you have cleared them in high humidity or rainy conditions. If you are driving into sun glare from bright sunlight, you can reduce glare and eyestrain by using sunglasses and/or sun visor.

To help others see you during heavy rain,… Use your low-beam headlights. A combination of standing water, speed, and tire conditions. Use low-beam headlights and reduce speed.

To avoid a side-impact collision, brake or accelerate quickly. Which emergency is best handled by shifting to NEUTRAL? a broken accelerator spring.

When your visibility is reduced for any reason, you need more time to use the IPDE process, ” ‘. ‘ . If you are driving into sun glare from bright sunlight you can reduce glare and eyestrain by using sunglasses and the sun visor.

What can you do to help others see you at dawn and dusk? Have your headlights on, so people can see your vehicle.

Straight down the middle of the road. If an approaching driver fails to dim their high beams, glance toward the right side of the road. This will keep you from being blinded by the other vehicle’s headlights and will allow you to see enough of the road to stay on course until the other vehicle has passed.

If a vehicle does not have ABS, name and describe the technique the driver should use to stop quickly. Use controlled braking by applying brakes to slow or quickly stop without locking the wheels. If there is a fire in the engine, use water to put it out. If you enter a curve too fast, brake hard.

MIT researchers have found an answer in a new study that shows humans need about 390 to 600 milliseconds to detect and react to road hazards, given only a single glance at the road — with younger drivers detecting hazards nearly twice as fast as older drivers.

However, a team of neuroscientists from MIT has found that the human brain can process entire images that the eye sees for as little as 13 milliseconds — the first evidence of such rapid processing speed. That speed is far faster than the 100 milliseconds suggested by previous studies.

The human brain can achieve the remarkable feat of processing an image seen for just 13 milliseconds, scientists have found. This lightning speed obliterates the previous record speed of 100 milliseconds reported by previous studies.

It’s caused by brain differences that make them take longer to do things than other kids. This includes doing homework, having a conversation, and making decisions like what to eat for breakfast. Slow processing speed can happen on its own. But it often co-occurs with ADHD, dyslexia , and anxiety.

Typical symptoms of brain fog include poor concentration, an extra effort to focus on a task, trouble multitasking or managing too many tasks at once, trouble tracking what you are doing (i.e., “Why did I just walk into this room?”) and trouble retrieving a memory or information.

Brain fog: Causes and tips. Brain fog can be a symptom of a number of medical conditions. It affects a variety of mental processes, including memory and concentration. It can occur with multiple sclerosis, during pregnancy, and as a result of lifestyle factors, such as stress, lack of sleep, or an unhealthful diet.
