How to Clear the End of the Driveway After the Plow Goes By
The ridge a city plow leaves is the hardest snow on your property. Here is why it is so dense, how to make it smaller before it forms, and how to take it apart safely.
Last updated: October 2026
Clear it soon, before it freezes, and take it in thin bites instead of one push. The ridge left by a street plow is compacted, wet and often salty, so it sets like concrete within hours. You can also shrink it before it forms by clearing a pocket on the side of the driveway the plow reaches first.
Why is the plow pile so hard to move?
It is not ordinary snow. Three things happen when a plow truck passes.
Compression. The blade squeezes the air out. A foot of fluffy snow becomes a few inches of dense material.
Mixing. It carries slush, road salt, sand and chunks of ice from the street.
Refreezing. Wet, salted snow that sits in the cold bonds into a solid mass.
The result weighs several times what the same volume of fresh snow weighs. It is the most common place for a back injury, a stalled machine or a broken shear pin.
Can you make the pile smaller before it forms?
Yes. This is the most useful trick, and many highway departments recommend it.
Stand in your driveway facing the street. Traffic on your side of the road comes from your left. The plow is carrying a blade full of snow as it approaches, and when it reaches the open gap of your driveway, that snow spills in.
Give it somewhere else to spill:
Clear a pocket on the left side of your driveway (the side traffic comes from), along the road edge. Ten feet or more is good.
The plow's load drops into the pocket before it reaches your driveway opening.
Less arrives at the driveway mouth.
Throw or pile your own snow on the right side, the downstream side, so the plow does not carry it back across the opening.
When should you clear it?
As soon as you safely can after the plow passes. Fresh plow snow is heavy but still loose. A few hours later, in freezing air, it is a block. If you know the plow's usual timing, plan the last clearing of the storm for just after it.
Never clear while plows or traffic are passing, and keep well back from the road.
How do you clear it by hand?
Carefully, or not at all. The American Heart Association warns that shoveling snow puts heavy strain on the heart, especially for people who are older, less active or have heart conditions, and advises pushing snow instead of lifting where possible and taking breaks. The plow pile is the heaviest shoveling there is.
If you do it by hand:
Slice, do not scoop. Cut the pile into small blocks.
Push each block to the side. Lift as little as possible.
Work from the top down on a tall ridge.
Stop and rest often. Stop altogether if you feel chest discomfort or shortness of breath, and seek medical help.
A two-stage machine is the right tool, because its metal auger breaks up packed snow before the impeller throws it. A single-stage paddle is not built for this. See single-stage vs two-stage.
Technique with any two-stage blower:
Take a partial width. Half the housing or less per pass.
Go slowly. Let the auger chew.
Shave from the top if the ridge is taller than the intake.
Aim the chute away from the street.
Expect a shear pin to break now and then. That is the pin doing its job. Keep spares. See what shear pins are.
What can a robot snow blower do with the pile?
Here is what the maker publishes, and where we stop.
Yarbo's Snow Blower is two-stage with a 24 inch path and a 12 inch intake, and Yarbo lists packed snow among the types it handles. So a plow ridge under 12 inches that has not frozen solid is within what the module is described as doing.
Yarbo does not publish a claim about street plow ridges, and we will not make one for it. A ridge taller than the intake, or one that has frozen hard overnight, may need to be broken up first or taken in more than one pass.

How do you set a robot up to deal with it?
Schedule a pass for after the plow. If your street is usually plowed by a certain hour, time a run to follow it, so the ridge is cleared while loose.
Run during the storm. A driveway kept clear in shallow passes leaves less of your own snow at the mouth to mix with the plow's.
Map the mouth with care. Keep the work area on your property and back from the travel lane. Follow Yarbo's guidance on boundaries near roads.
A light plow blade is the wrong tool for a frozen ridge. Mowrator positions the S1 4WD Snow Plow Kit for powder, packed snow, slush and light ice in light to moderate amounts. It can push a fresh, low ridge aside. It will not move a tall frozen one.
What should you never do?
Do not throw or push snow into the street. It is illegal in many places and dangerous for drivers.
Do not bury the hydrant, mailbox or storm drain.
Do not reach into a clogged chute or auger with your hands. Stop the machine and use a clearing tool. Yarbo sells a Snow Shovel tool for clearing buildup from its snow blower.
Do not let children play in the ridge by the road. Plow drivers cannot see them.
Does salt help?
Salt lowers the temperature at which the ridge refreezes, which buys you time. It does not remove the snow. Use it sparingly near lawns, plants and concrete, and check what is safe for your surface.
What is a realistic plan?
Before winter, mark the driveway edges and decide where snow will go.
During storms, keep the driveway clear in shallow passes.
Clear a pocket upstream of the driveway mouth.
After the plow passes, clear the ridge the same day.
Take it in bites, by machine where you can.
If you want help choosing a machine for a driveway that gets heavy plow ridges, tell us how wide the mouth is, how tall the ridge usually gets and when your street is plowed. We will say plainly what a robot can take on and what it cannot. See do robot snow blowers work? and the robot snow blower collection.

Frequently asked questions
Why is the snow at the end of the driveway so heavy?
A street plow compresses the snow, mixes in slush, salt and ice, and leaves it to refreeze. It can weigh several times as much as fresh snow.
How do I stop the plow from blocking my driveway?
You cannot stop it fully, but you can reduce it. Clear a pocket along the road on the side traffic comes from, so the plow's load drops there before it reaches your driveway.
When should I clear the plow pile?
As soon as it is safe after the plow passes, before it freezes solid.
Can a snow blower clear the plow pile?
A two-stage blower can, taken slowly in partial-width passes. Its metal auger breaks up packed snow. Keep spare shear pins.
Can a Yarbo clear the plow ridge?
Yarbo lists packed snow and a 12 inch intake. It does not publish a claim about plow ridges. A ridge that is taller than the intake or frozen solid may need breaking up first.
Is it illegal to push snow into the street?
In many places, yes, and it is dangerous for drivers. Keep cleared snow on your own property.
