An &#8220;N&#8221; endorsement is required for certain vehicles that transport liquids or gases. The liquid or gas does not have to be a HazMat. An &#8220;N&#8221; endorsement is required if your vehicle needs a Class A, B, or C CDL and you want to haul a liquid or liquid gas in a tank or tanks having an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1000 gallons or more that is either permanently or temporarily attached to the vehicle or chassis.&nbsp;<\/p>\n<p><\/p>\n<p dir=\"ltr\">A CMV transporting an empty storage container tank not designed for transportation, with a rated capacity of at least 1,000 gallons that is temporarily attached to a flatbed trailer, is not a tank vehicle (CVC \u00a715210(r)).<\/p>\n<p dir=\"ltr\">Before loading, unloading, or driving a tanker, inspect the vehicle. This makes sure that the vehicle is safe to carry the liquid or gas and is safe to drive.<\/p>\n<p dir=\"ltr\">A CLP holder with an &#8220;N&#8221; endorsement (N) is prohibited from operating a tank vehicle unless it is empty. In addition, if the tanker previously contained HazMat, it must be purged (FMCSR \u00a7383.25).<\/p>\n\n\n<p>If an applicant applies for a Class C CDL with an \u201cN\u201d endorsement <strong>only<\/strong>, a commercial skills test is required. The applicant must be tested in a representative Class C CMV designed to transport any liquid or gaseous materials in a tank or tanks having an individual rated capacity of more than 119 gallons and an aggregate rated capacity of 1,000 gallons or more that is permanently or temporarily attached to the vehicle or chassis.<\/p>\n\n\n\n<p>An \u201cN\u201d endorsement may be added to an existing Class C CDL with the completion of all applicable knowledge tests; the commercial skills test is <strong>not<\/strong> required.<\/p>\n\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.1 \u2013 Inspecting Tank Vehicles<\/h3>\n\n\n<p dir=\"ltr\">Tank vehicles have special items that you need to check. Tank vehicles come in many types and sizes. You need to check the vehicle\u2019s operator manual to make sure you know how to inspect your tank vehicle.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.1.1 \u2013 Leaks<\/h3>\n\n\n<p dir=\"ltr\">On all tank vehicles, the most important item to check for is leaks. Check under and around the vehicle for signs of any leaking. Do not carry liquids or gases in a leaking tank. To do so is a crime. You will be cited and prevented from driving further. You may also be liable for the cleanup of any spill. In general, check the following:<\/p>\n\n\n<ul class=\"wp-block-list\"><li>Check the tank\u2019s body or shell for dents or leaks.<\/li><li>Check the intake, discharge, and cut-off valves. Make sure the valves are in the correct position before loading, unloading, or moving the vehicle.<\/li><li>Check pipes, connections, and hoses for leaks, especially around joints.<\/li><li>Check manhole covers and vents. Make sure the covers have gaskets and they close correctly. Keep the vents clear so they work correctly.<\/li><\/ul>\n\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.1.2 \u2013 Check Special Purpose Equipment<\/h3>\n\n\n<p dir=\"ltr\">If your vehicle has any of the following equipment, make sure it works:<\/p>\n\n\n<ul class=\"wp-block-list\"><li>Vapor recovery kits.<\/li><li>Grounding and bonding cables.<\/li><li>Emergency shutoff systems.<\/li><li>Built in fire extinguisher.<\/li><\/ul>\n\n\n<p dir=\"ltr\">Never drive a tank vehicle with open valves or manhole covers.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.1.3 \u2013 Special Equipment<\/h3>\n\n\n<p dir=\"ltr\">Check the emergency equipment required for your vehicle. Find out what equipment you are required to carry and make sure you have it (and it works).<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2 \u2013 Driving Tank Vehicles<\/h3>\n\n\n<p dir=\"ltr\">Hauling liquids in tanks requires special skills because of the high center of gravity and liquid movement. See Figure 8.1.<\/p>\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"492\" height=\"284\" src=\"https:\/\/www.dmv.ca.gov\/portal\/uploads\/2020\/04\/comlhdbk_img_104.jpg\" alt=\"a tank vehicle next to a regular vehicle\" class=\"wp-image-13222\" srcset=\"https:\/\/www.dmv.ca.gov\/portal\/uploads\/2020\/04\/comlhdbk_img_104.jpg 492w, https:\/\/www.dmv.ca.gov\/portal\/uploads\/2020\/04\/comlhdbk_img_104-300x173.jpg 300w, https:\/\/www.dmv.ca.gov\/portal\/uploads\/2020\/04\/comlhdbk_img_104-450x260.jpg 450w\" sizes=\"auto, (max-width: 492px) 100vw, 492px\" \/><\/figure>\n\n\n<p dir=\"ltr\"><strong>Figure 8.1 <\/strong><\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.1 \u2013 High Center of Gravity<\/h3>\n\n\n<p dir=\"ltr\">High center of gravity means that much of the load\u2019s weight is carried high up off the road. This makes the vehicle top-heavy and easy to roll over. Liquid tankers are especially easy to roll over. Tests have shown that tankers can turn over at the speed limits posted for curves. Take highway curves and on ramp\/off ramp curves well below the posted speeds.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.2 \u2013 Danger of Surge<\/h3>\n\n\n<p dir=\"ltr\">Liquid surge results from movement of the liquid in partially filled tanks. This movement can have bad effects on handling. For example, when coming to a stop, the liquid will surge back and forth. When the wave hits the end of the tank, it tends to push the truck in the direction the wave is moving. If the truck is on a slippery surface, such as ice, the wave can shove a stopped truck out into an intersection. The driver of a liquid tanker must be very familiar with handling the vehicle.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.3 \u2013 Bulkheads<\/h3>\n\n\n<p dir=\"ltr\">Some liquid tanks are divided into several smaller tanks by bulkheads. When loading and unloading smaller tanks, the driver must pay attention to weight distribution. Do not put too much weight on the front or rear of the vehicle.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.4 \u2013 Baffled Tanks<\/h3>\n\n\n<p dir=\"ltr\">Baffled liquid tanks have bulkheads in them with holes that let the liquid flow through. The baffles help to control the forward and backward liquid surge. Side-to-side surge can still occur this can cause a roll over.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.5 \u2013 UnBaffled Tanks<\/h3>\n\n\n<p dir=\"ltr\">Unbaffled liquid tankers (sometimes called \u201csmooth bore\u201d tanks) have nothing inside to slow down the flow of the liquid. Therefore, forward-and-back surge is very strong. Unbaffled tanks are usually those that transport food products (milk, for example). (Sanitation regulations forbid the use of baffles because of the difficulty in cleaning the inside of the tank.) Be extremely cautious (slow and careful) in driving smooth bore tanks, especially when starting and stopping.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.6 \u2013 Outage<\/h3>\n\n\n<p dir=\"ltr\">Never load a cargo tank totally full. Liquids expand as they warm and you must leave room for the expanding liquid. This is called \u201coutage.\u201d Since different liquids expand by different amounts, they require different amounts of outage. You must know the outage requirement when hauling liquids in bulk.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.7 \u2013 How Much to Load?<\/h3>\n\n\n<p><\/p>\n<p dir=\"ltr\">A full tank of dense liquid (such as some acids) may exceed legal weight limits. For that reason, you may often only partially fill tanks with heavy liquids. The amount of liquid to load into a tank depends on:<\/p>\n<p><\/p>\n\n\n<ul class=\"wp-block-list\"><li>The amount the liquid will expand in transit.<\/li><li>The weight of the liquid.<\/li><li>Legal weight limits.<\/li><li>The temperature of the load.<\/li><\/ul>\n\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.8 \u2013 Speeding in a Tank Vehicle<\/h3>\n\n\n<p dir=\"ltr\">If you are driving a tank vehicle transporting more than 500 gallons of flammable liquid at a speed greater than the applicable speed limit or in willful or wanton disregard for the safety of persons or property, in addition to any other applicable penalty, you are subject to a fine for a first offense. For a second or subsequent offense within 2 years of a prior offense, you are subject to a fine of not less than $2,000 and a suspension of up to 6 months of a HazMat or cargo &#8220;N&#8221; endorsement, or both (CVC \u00a722406.5).<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.2.9 \u2013 Hours of Service in a Tank Vehicle<\/h3>\n\n\n<p dir=\"ltr\">The maximum driving time within a work period is 10 hours for drivers of tank vehicles with a capacity greater than 500 gallons when transporting flammable liquid (CVC \u00a734501.2(b)(1)).<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.3 \u2013 Safe Driving Rules<\/h3>\n\n\n<p dir=\"ltr\">In order to drive tank vehicles safely, you must remember to follow all the safe driving rules. A few of these rules are:<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.3.1 \u2013 Drive Smoothly<\/h3>\n\n\n<p dir=\"ltr\">Because of the high center of gravity and the surge of the liquid, you must start, slow down, and stop very smoothly. Also, make smooth turns and lane changes.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.3.2 \u2013 Controlling Surge<\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>Keep a steady pressure on the brakes. Do not release the brakes too soon when coming to a stop.<\/li><li>Brake far in advance of a stop and increase your following distance.<\/li><li>If you must make a quick stop to avoid an accident, use controlled or stab braking. If you do not remember how to stop using these methods, review <a href=\"https:\/\/www.dmv.ca.gov\/portal\/es\/handbook\/commercial-driver-handbook\/section-2-driving-safely\/\" target=\"\" title=\"Section 2\" rel=\"noopener noreferrer\">Section 2<\/a>. Also, remember that if you steer quickly while braking, your vehicle may roll over.<\/li><\/ul>\n\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.3.3 \u2013 Curves<\/h3>\n\n\n<p dir=\"ltr\">Slow down before curves, and then accelerate slightly through the curve. The posted speed for a curve may be too fast for a tank vehicle.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.3.4 \u2013 Stopping Distance<\/h3>\n\n\n<p dir=\"ltr\">Keep in mind how much space you need to stop your vehicle. Remember that wet roads double the normal stopping distance. Empty tank vehicles may take longer to stop than full ones.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">8.3.5 \u2013 Skids<\/h3>\n\n\n<p dir=\"ltr\">Do not over steer, accelerate, or brake. If you do, your vehicle may skid. On tank trailers, if your drive or trailer wheels begin to skid, your vehicle may jackknife. When any vehicle starts to skid, you must take action to restore traction to the wheels.<\/p>\n\n\n<div class=\"wp-block-dmv-spacer-block spacer-box\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading\">Section 8<\/h3>\n\n\n<p dir=\"ltr\"><strong>Test Your Knowledge<\/strong><\/p>\n\n\n<ol class=\"wp-block-list\"><li>How are bulkheads different than baffles?<\/li><li>Should a tank vehicle take curves, on ramps, or off ramps at the posted speed limits?<\/li><li>How are smooth bore tankers different to drive than those with baffles?<\/li><li>What 3 things determine how much liquid you can load?<\/li><li>What is outage?<\/li><li>How can you help control surge?<\/li><li>What 2 reasons make special care necessary when driving tank vehicles?<\/li><\/ol>\n\n\n<p dir=\"ltr\">These questions may be on the test.
