🌧️ Wet Roads, Yellow Buses and Sun in Your Eyes: Your Roads & Commute Report

Or: How to Drive Through a Soggy Weekend and Ease Back Into the School Run

Driving in the fall is a lot like cooking on a wood stove. Most days it’s easy, but the heat changes on you now and then, and you have to pay a little more attention. This week the change comes from the weather. After a long dry spell, a soaking rain is headed our way for the weekend, and then school buses roll again on Monday.

Here’s what’s in this week’s report: how to handle the wet roads Isaias’s leftover rain will bring Saturday and Sunday, a refresher on stopping for school buses as fall break ends, simple tricks for the low fall sun that blinds you at drive time, the road work you’ll pass heading north on U.S. 127 to Crossville and what Chattanooga drivers will see this week, including a Wilcox Tunnel closure. The repaving on SR-111, SR-399 and SR-8 here at home is still underway, just as we reported Tuesday.

⏱️ What this means for you in 30 seconds

• Driving this weekend? Rain is likely Saturday afternoon through Sunday. Slow down, skip the cruise control, turn your headlights on and never drive into water over the road.
• Back to school Monday, Oct. 12? When a school bus stops with red lights flashing, stop. On a two-lane road, that means traffic going both ways.
• Sun in your eyes at dawn or dusk? Keep sunglasses in the truck, clean the inside of the windshield and leave extra room.
• Headed to Crossville? Expect work zones on U.S. 127 north of I-40 and night paving on I-40.
• Going to Chattanooga? The Wilcox Tunnel closes in the daytime Thursday and Friday and again Sunday.
• Driving around the county? Flaggers are still out on SR-111, SR-399 and SR-8. Leave five extra minutes.

🌧️ The First Real Rain in Weeks: Easy Does It on Wet Roads This Weekend

The leftovers of Tropical Storm Isaias are expected to reach the Valley this weekend. As of Wednesday afternoon, the National Weather Service forecast for Dunlap calls for a few showers late Friday night, showers and thunderstorms likely Saturday afternoon with gusts up to 30 mph, and a 90 percent chance of showers and storms Saturday night and Sunday. Things dry out Sunday night.

AAA says wet pavement plays a part in nearly 1.2 million crashes a year, and its advice is simple. Slow down, leave more room, don’t use cruise control on wet roads and avoid hard braking or sharp turns. If you feel the car start to slide, look and steer where you want to go and stay off the brakes. Tennessee law also says your headlights must be on any time rain makes you run your wipers steadily.

What it means for you: A road that’s been dry for weeks is like a cast-iron skillet that’s never been wiped out. The first rain lifts up everything that’s settled on it, so the road can be slicker than you’d expect. Take curves and mountain grades a little slower, and if water is running across the road, turn around. The Weather Service says just 12 inches of moving water can carry away most cars. If your family is coming home from the Gulf Coast after fall break, try to be home before the rain sets in on Saturday.

🚌 Fall Break Ends, the Buses Roll Again: A Quick Refresher on Stopping

Sequatchie County students head back to class Monday, Oct. 12, and that means big yellow buses back on our roads at dawn and in the afternoon. Under Tennessee law, when a school bus stops to pick up or drop off children with its red lights flashing and stop arm out, drivers coming from either direction have to stop and stay stopped until the bus starts moving, the driver waves you on or the lights go off.

There’s one exception. If you’re on a divided highway, where a grass median or barrier separates the two sides, traffic on the other side of the median doesn’t have to stop. A painted center turn lane doesn’t count as a divider, so on a road like that, everybody stops. Yellow flashing lights mean the bus is getting ready to stop, so slow down and get ready.

What it means for you: Think of that stop arm like a mama hen spreading her wings. When it’s out, little ones are crossing, and everybody waits. It only takes a minute, and it’s the law. National School Bus Safety Week is Oct. 19 to 23, with the theme “Safe Rides, Everyday Heroes,” so it’s also a nice time to thank your child’s bus driver.

🌅 That Low Fall Sun: How to See the Road When It’s Right in Your Eyes

This time of year, the sun sits low in the sky right when lots of us are driving to work or heading home. AAA says the glare is worst just after sunrise and just before sunset, and it asks drivers to slow down and take extra care in school zones when the sun is a problem. Its tips:

• Keep a pair of polarized sunglasses in the car.
• Use your sun visor.
• Leave more room behind the car ahead, since glare makes it hard to see brake lights.
• Drive with your headlights on so others can see you.
• Keep the windshield clean inside and out, and don’t pile papers on the dashboard, since they reflect onto the glass.
• If it’s hard to see, follow the lane lines to stay on course.

What it means for you: A hazy windshield in the low sun is like reading the paper through a dusty screen door. A two-minute wipe on the inside of the glass makes a big difference. Remember, too, that clocks fall back an hour on Sunday, Nov. 1, so the sun will shift on the evening drive home before long.

🧭 Headed North on U.S. 127 to Crossville? Here’s What You’ll Pass

Lots of Valley folks drive up the mountain to Crossville for shopping, doctor visits and fall outings like the Upper Cumberland Bigfoot Festival on Oct. 17 and 18. TDOT’s weekly report for Oct. 1 to 7 lists these jobs in Cumberland County:

• U.S. 127 (SR-28) north of I-40 to near Potato Farm Road: Bridge building, grading and paving continue. Expect trucks entering and leaving the work zone and possible short stops with flaggers. Lawson Road is closed, with a detour on Tabor Road.
• I-40 from about mile marker 306 to 311: Resurfacing at night, Sunday night through Friday morning, 7 p.m. to 6 a.m.
• Main Street (SR-28) in Crossville, from Miller Avenue toward Elmore Road: Final work on the resurfacing job, possibly at night, 7 p.m. to 6 a.m., with lane closures and flaggers.
• SR-24 at the Obed River bridge: Closed for a bridge replacement for the length of the project, with the detour on SR-462 and SR-1.
• Main Street under I-40 near Crab Orchard: Bridge repairs that started Oct. 5, with one lane closed and a temporary signal.

What it means for you: Most of this is like a busy church parking lot on Sunday. You’ll move along, just a little slower, so give yourself an extra ten minutes. Daytime trips on I-40 shouldn’t run into the paving, since that work happens overnight.

❓ Frequently Asked Questions

Do I really have to turn on my headlights in the rain?

Yes. Tennessee law says your headlights must be on any time rain, mist or snow makes you run your wipers steadily. It also helps other drivers see you.

Do I have to stop for a school bus on the other side of the road?

On a regular two-lane road, yes. You only skip the stop if a grass median or barrier separates you from the bus. A center turn lane isn’t a separator, so you still stop.

What does it mean when a school bus has yellow lights flashing?

The bus is about to stop. Slow down and get ready to stop when the red lights come on.

How much water on the road is too much?

The National Weather Service says 12 inches of moving water can carry away most cars, and less can stall them. If you can’t see the road under the water, turn around.

Will the I-40 paving near Crossville slow me down during the day?

It shouldn’t. TDOT lists that work for nights, Sunday through Friday morning, 7 p.m. to 6 a.m. The U.S. 127 work north of I-40 can have daytime stops, though.

When is the Wilcox Tunnel closed?

Thursday and Friday, Oct. 8 and 9, from 8:30 a.m. to 3 p.m., and Sunday, Oct. 11, from 7 a.m. to 4 p.m.

Where’s the quickest place to check road conditions?

The TDOT SmartWay map at smartway.tn.gov, or dial 511 from your phone for statewide travel information.

🌻 A Little Extra Care Goes a Long Way

You don’t need to memorize every closure or every law. Slow down when the road is wet, stop when the bus stops, wipe the windshield and check the map before a long trip. Do those few things, and the rain, the buses and the low sun won’t give you a bit of trouble this week.
