How thick does ice have to be to hold 200 pounds?
At 4” the ice is suitable for ice fishing, cross-country skiing and walking and can support about 200 pounds. At 5 inches of new clear ice should be enough to hold a single snowmobile or ATV or about 800 pounds. At 8-12 inches the ice should be suitable for a small car or a larger group of people.
Consider your guest count. We recommend planning between 1 and 2 pounds of ice per person, based on the type of event and your need for the ice, serving vs cooling. The type of event you're hosting or attending matters.
General Ice Thickness Guidelines
2 inches thick The ice is very susceptible to breakage and is not safe to walk on. 4 inches thick It should be ok to stand, skate, and ice fish on the surface.
As a general rule of thumb, ice is safe to walk on when there is 4 inches or more of clear ice. It is important to understand that different types of ice varying in their strength. Clear blue or black ice is the strongest. This ice is formed from the lake water freezing.
Once you have the proper tools and safety gear for fishing on the ice, consider these general safe ice fishing, or safe ice thickness guidelines. Stay off of any ice that is 3 inches or less thick. Remember that a minimum of 4 inches of clear, solid ice is a requirement to support an average person's weight.
Safe thicknesses for different vehicles include: If the ice is 5 to 7 inches deep, it's safe to drive a snow machine or ATV on it. If the ice is 8 to 12 inches deep, it's safe to drive a UTV, car or small pickup truck on it. To drive a medium truck on the ice, it should be at least 12 to 15 inches thick.
8-12 inches is needed for normal passenger vehicles. For snowmobiling, a minimum of 5 inches is recommended. And finally, for anyone walking or ice-fishing, 4 inches is what is needed to make the ice safe.
At its melting point, ice has a Mohs hardness of 2 or less, but the hardness increases to about 4 at a temperature of −44 °C (−47 °F) and to 6 at a temperature of −78.5 °C (−109.3 °F), the vaporization point of solid carbon dioxide (dry ice).
Re: Is lake ice thicker in the middle or close to shore? Ice on the edge is limited to the depth of the water at the edge. So it is always thicker towards the middle.
o Light to dark black- Indicates melting ice and can occur even if temperatures are below 32 degrees. It's not safe to walk on this ice. o White to opaque- This color indicates water-saturated snow that has frozen on top of ice forming another thin ice layer.
How do you know if ice is thick enough?
Use a tape measure to find ice's true thickness. Put the tape measure into the hole and hook the bottom edge of ice before taking measurement. You can also use an ice fisherman's ice skimmer with inch markings on the handle in place of the tape measure.
2 ½ ton truck – 8 inches. 3 ½ ton truck – 9 inches. 7-8 ton truck – 10 inches. ATV/Snowmobile – 4 inches.
Work on the road starts soon after Christmas. When the ice is 1 meter (42 inches) thick, it can support a truck fully loaded with over 40 metric tons (44 tons) of fuel. Full trucks traveling north have a strict speed limit of 25 kilometers (15.5 miles) per hour.
As the chart above shows, ice needs to be at least 8 inches thick to hold a small pickup ruck. Also, don't drive in a group. Park cars at least 50 feet apart or more and move every couple hours.
If you aren't sure, stay on shore. Ice may form quickly when temperatures tumble, but it takes more time than you might think for ice to reach the four-inch thickness that experts recommend. On average, it takes four days of below freezing temperatures to form ice that is safe.
2. Based on studies, once a thin layer of ice film forms on a lake, it will add 1 inch of ice for every 15 freezing degree days in a 24 hour period.
1 Hour – Hypothermia
If you can keep your airway above water with the sleeves of your jacket or your hair freezing to the ice, you may survive another hour or more before dying from hypothermia.
Less than 4 inches: Stay off the ice. 4 inches: Walking, ice fishing, ice skating, or other activities on foot are permitted. 5 to 7 inches: Snowmobiling or riding ATVs are safe. 8 to 12 inches: Driving a car or small pickup is allowed.
4 inches – a minimum of 4 inches thick is considered safe for ice fishing and other recreational activities on foot. 5-7 inches – at 5-7 inches thick, ice is considered safe enough for a snowmobile or ATV.
The best time of day to ice fish is during the first couple of hours after sunrise, and for about 2 hours both before and after sunset. These are the times when most fish are heading to their feeding grounds, and when most species are active.
How much ice do I need for a 1 ton truck?
You need at least 15″ imho. The snow on top will hurt the quality as well. 18″ clear black ice for my truck is a minimum and I would prefer 20 and better!
You need at least 5” for an ATV and 8” for a UTV. Remember, ice thickness varies from place to place on a frozen lake. Stay cautious and stay safe. These guidelines apply to new, clear ice only.
Staying Safe Ice Fishing With The Polaris Ranger
Although 5-6 inches of clean ice -- or 8-10 inches of cloudy / slushy ice -- should be sufficient to hold the Polaris Ranger, you should always consult a certified ice thickness chart before riding your side-by-side over a frozen lake.
If you're buying a bag of ice at a store where ice has been made in the back room and scooped into generic bags, the risk may be higher. In fact, Ice can and will go bad. Because it is a type of frozen food, ice can become contaminated with bacteria – from Salmonella and E. coli to Hepatitis A – that can cause illness.
Ice thickness can vary over a single body of water; it may be a foot thick in one location and only an inch or two a few feet away. Use an ice chisel, auger, or cordless drill to make a hole in the ice.
The thing is, ice isn't stronger than steel. A block of steel will destroy a block of ice.
Ice VII is a cubic crystalline form of ice. It can be formed from liquid water above 3 GPa (30,000 atmospheres) by lowering its temperature to room temperature, or by decompressing heavy water (D2O) ice VI below 95 K.
Thus ice is softer than rock. It is because the ice's hardness measured on the Mohs scale of hardness of minerals is 1.5 while the hardness of the minerals ranges from 1 to 10. Thus all minerals are harder than the ice.
The ice then acts like a greenhouse to the lake water, and as the sun shines on the ice, it heats the water underneath the ice. The ice then starts to melt from the bottom, where it is touching the water.
For a round lake of about a mile across, warming 20° F would expand the ice sheet by about four feet. That expansion causes the ice to crack and deform and this causes vibration of the ice that you hear as sounds. Likewise, when it cools again it will contract, crack and deform making similar sounds.
Do lakes freeze from center out?
Water freezes from the perimeter of the lake to the center. It happens this way because the water is shallower at the lake's edge so it cools off faster. Water is most dense at 39 degrees Fahrenheit, so when it gets colder than that, the cold, lighter water floats on top of the lake.
- Wear boots or slip-resistant shoes. ...
- Watch out for black ice which forms when wet pavement freezes. ...
- Use your arms to keep yourself stable and balanced when walking on ice. ...
- Be mindful of where you park and be careful getting out of your car.
Stay prone and roll away.
Distribute your weight across the ice as much as possible. Roll out the way you came in. This will continue to distribute your weight and get you out as quick and safely as possible.
It is possible to have ice that is too hard and cold. Often this is found on outdoor lakes, ponds, and community rinks and is characterized by ice chipping and flaking in shards rather than making snow. If you've ever skated on overly hard ice, you know it is fast, but can be dangerous when it chips away!
The ice is only about one inch thick when everything is finished. In addition, the official size of a National Hockey League rink is 200 feet long and 85 feet wide. To make the an ice sheet with this large of a surface area requires about 10,600 gallons of water.
With 4 inches of new, clear ice, an average-sized angler is generally safe to venture out on foot. Anything less than 4 inches is considered too risky. Many avid ice anglers look forward to first ice as the fish are often eager to bite.
When the ice is two inches (or less) in thickness, don't leave the shore. Three inches is your bare minimum for ice thickness. Four inches (or more) is recommended for walking, skating and ice fishing on foot. Five inches (and thicker) is generally safe for ATVs and snowmobiles.
12”-14” of ice.
There's a clever little period of exposition where Midthunder's character explains to the company's insurance agent (Walker) that the truckers use bobbleheads on their dashboard as an indication for speed. Too fast and they may hit a pressure wave causing the pressure to break the ice, which will sink the truck.
The ice roads are much safer than they are portrayed to be. Trucks do fall through the ice every couple of seasons. Real seasons that is. But they are usually the Snowcats that are sent out first to clear the way.
How much money do Ice Road Truckers make?

At 5 inches of new clear ice should be enough to hold a single snowmobile or ATV or about 800 pounds. At 8-12 inches the ice should be suitable for a small car or a larger group of people. Light pickup trucks or SUV's should be ok on new clear ice 12-15” thick.
A one-inch layer of water or ice weighs approximately five pounds per square foot.
It is recommended that you drive 10 to 15mph under most circ*mstances. Following closely behind other cars is not recommended, since you may interrupt their wave action with your own, causing a break in what would otherwise be sound ice.
According to the Department of Natural Resources, 12-15 inches of solid ice is needed to safely drive a truck onto a lake or pond. 8-12 inches is needed for normal passenger vehicles. For snowmobiling, a minimum of 5 inches is recommended.
I did a quick calculation and it said that a 5ft cube of ice (used 0.918 gram/cm3 for density) could support a weight of about 290kg or 640lbs without sinking.
This is the time of year when many accidents occur as people fall through the ice in unsafe conditions. As a rule, no one should venture out on any ice when it is less than 2 inches thick. When going out on the ice for the first time, only do so after a hard freeze that forms clear solid ice.
Ice thickness can vary over a single body of water; it may be a foot thick in one location and only an inch or two a few feet away. Use an ice chisel, auger, or cordless drill to make a hole in the ice.
2 ½ ton truck – 8 inches. 3 ½ ton truck – 9 inches. 7-8 ton truck – 10 inches. ATV/Snowmobile – 4 inches.

As a rule of thumb, snow weighs approximately 20 pounds per cubic foot, or 1.25 pounds per inch of depth.
Ice, solid weighs 0.919 gram per cubic centimeter or 919 kilogram per cubic meter, i.e. density of ice, solid is equal to 919 kg/m³. In Imperial or US customary measurement system, the density is equal to 57.371 pound per cubic foot [lb/ft³], or 0.5312 ounce per cubic inch [oz/inch³] .
1 gallon of water weighs 8.3454 lbs (3.7854 kg). But REMEMBER the important caveat about temperature above! 2 gallons of water weighs 16.69 lbs (7.57 kg) 3 gallons of water weighs 25.04 lbs (11.36 kg)
