Can You Pass at the Top of a Hill?
No. You may not pass when you are going up a hill and getting close to the top. Near the crest you cannot see what is coming from the other side, so a car you can't see yet may be driving straight at you. This rule applies in California, Florida, Texas, New York, Pennsylvania and every other US state.

Twenty seconds on a two-lane road
You're running late. Your friends are already there, your phone keeps buzzing on the seat next to you, and in front of you a heavy truck is crawling up a long hill. Slowly. Painfully slowly.
The road is narrow: one lane each way. And here is the tempting part - there is no line in the middle. Nothing says you can't. The other lane looks empty. Your hand is already on the turn signal.
Here is what you can't see. On the other side of the hill, a pickup is climbing toward the same crest. Its driver is heading home after a long day, where someone has kept dinner warm. He isn't doing anything wrong. He is in his own lane.
For the next few seconds the hill is a wall between you. Neither of you knows the other exists.
Now the other ending. You take your hand off the signal and stay behind the truck. Twenty seconds later the road levels out, the pickup goes by in the other lane, you notice it for a moment and forget it. You arrive a minute later than you wanted. Nobody will ever know that those twenty seconds mattered - and that is exactly how it should be.

Why the top of a hill is the most deceptive place on the road
A hilltop doesn't look dangerous. It looks empty. That is the trick: the road beyond the crest is not empty, it is just hidden. Add a truck in front of you and you are blind twice - the truck hides the road ahead, and the hill hides everything behind it.
And when two cars meet head-on, their speeds add up. Neither driver has the time or the space to stop. Passing on a hill is one of the few mistakes you may not get a second chance to learn from.
No line doesn't mean "yes"
Many new drivers think "no marking means passing is allowed". It doesn't. The rule is about what you can see, not about the paint. Passing near the top of a hill without a clear view of the road ahead is illegal in CA, FL, TX, NY, PA and every US state, whether or not there is a line on the road. And on any road in the world the danger is exactly the same.
The paint that warns you: a no-passing zone
Before most hilltops the road tells you the answer in advance: a solid yellow line on your side, very often a double solid yellow. A solid yellow line on your side means you must not cross it to pass. Think of it as the road whispering: "I know something you don't."
📱 In the Epic Auto School app: lesson “Road Markings” → “Double Yellow Lines (Solid + Broken)”. Right here the lesson pauses and asks you: “Why is overtaking not allowed if the broken line is not on your side?”
So when is passing OK?
Only when the line on your side is broken and you can see far enough ahead to finish the pass safely, with no oncoming traffic, before you need to return to your lane. If you have to guess, you can't see far enough.

What the driver handbooks say, state by state
- California: before you pass near a hill, curve, intersection or obstruction, you must have a clear view of at least one-third of a mile ahead.
- Florida: before passing near a hill or curve, you must have a clear view of at least 500 feet ahead.
- Texas and New York: before passing near a hill, curve, intersection or obstruction, you must have a clear and unobstructed view of the road ahead.
- Pennsylvania: you may not pass when you are approaching or on a hill crest or curve that restricts your view of oncoming traffic.
📱 In the Epic Auto School app: lesson “Passing” → “Overtaking Risks: Hills, Curves, and Unseen Dangers”. Right here the lesson pauses and asks you: “How much clear view should you have to execute a pass safely?”
A test question that is really a life question
Yes, this is on the DMV written test, and now you know the answer. But one day there will be no test - just you, a slow truck, a hill and a hurry.
When that day comes, remember: on the other side of the hill someone is driving home to the people who love them. And at the end of your own road there are people waiting for you - and people you love. Twenty seconds behind a truck is a small price for both of you to get there.
