    • i am doing an eagle scout project and would like to know what is the best way to fit in a lot of cars would the typical straight lines for parking stalls work better than the slanted ones so please let me know asap thank you

      Angled parking versus ninety degree parking is a common issue in our industry. It is difficult to tell you which design works best for your project without analyzing the existing conditions. Four main factors will determine which is best: the shape of the lot, the dimensions of the lot, the traffic flow situation, and on-site obstructions. Typically, ninety degree parking will allow for more stalls if the lot is rectangular or square. However, if the parking is narrow and long then angled parking will often allow the designer to maximize parking while achieving a safe and effective traffic flow. Please remember there is always an exception to the rule and each parking lot is unique. It may help if you visit a lot that is similar to the one for your project and see if the same rules, or design, can apply to your lot. Please visit our Standards page for more information that may assist you in your endeavor. Good luck!!

    • Is there a code for how small parking spaces can be in 91301 zip?

      Thanks for the great question! Agoura Hills is represented by the zip code 91301 and their municipal code specifies parking stall dimensions. The minimum width and length of a standard parking stall at a ninety degree angle is 8’6″ by 18′. Agoura Hills does allow compact parking; however, these smaller parking stalls must be approved by the planning commission and will probably require a permit issued by the city. The minimum size of a compact stall at ninety degrees is 8’6″ in width and 15′ in length. In addition, a maximum of thirty percent of the total amount of stalls may be compact. Finally, the stalls must be labeled “compact” with stencils. I hope this information helps you. If you have any other questions please contact us again.

    • What is the best way to paint a handicap sign in a parking stall that is rarely hit by the sun throughout the day. We have painted it three times and it keeps flaking and chipping. Help!

      Typically, the most recent coat of paint is only as good as the previous coats. Meaning, if you are experiencing flaking or chipping then the problem will persist. In light of recent economic challenges, I recommend diligently scraping the existing peeling and flaking paint as an inexpensive “do-it-yourself” method. Another option is to rent a pressure washer and wand over the compromised areas. Allow sufficient dry time and then re-stripe with a paint designed for parking lot use. If you have an asphalt parking lot, please make sure that the paint is not failing due to oil, or grease build-up. Please keep in mind that you may be experiencing these problems because the surface is too smooth. Smooth surfaces do not allow the paint to properly bond. If you have a concrete parking lot, you may want to consider etching the surface via shotblasting. You can also etch the asphalt; however, sandblasting may be more effective than shotblasting. Unfortunately, sandblasting is a very messy and expensive process. Please call for further discussion. Thanks!

    • Hi Would you be able to tell me the demensions of the parking area for a semi truck( bobtail), a tractor and long trailer, and just a long trailer? I am doing a school project and trying to design a parking lot for truckdrivers, but have no clue what the striping area is or how many i can get in an area. thanks you for your help Connie

      Striping dimensions for big rigs, long trailers, and semi-trucks may be dictated by a city’s municipal code. However, many cities do not have a code drafted for truck parking. For new construction sites, architects will typically require a 10′ to 12′ width for over-sized vehicles. This is mainly dependent upon the nature of the stalls and the facility. Length of the parking line is determined by the length of the over-sized vehicle. The length of the stall is typically in five or ten foot increments (i.e. thirty-five feet or fifty feet). For example, the city of Vernon, CA requires a minimum of a 10′ wide by 75′ length and a 15′ vertical clearance. Further more, the city of Vernon requires one truck loading space per every 10,000 square feet of gross floor area (for warehouses and industrial use). For reference, please visit The main factor to consider is SAFETY! Make considerations for issues such as turning radius and designing lines that are long enough to provide a guide for backing-in or out of a stall. Good luck with your project!

    • I am a U.S. Marine stationed overseas, we need to repaint vehicle barriers and curbs yellow, wanted to know what paint is recommended and a source, best for heat and humidity. Please assist at your earliest.

      For curbs and concrete barriers, a standard water based traffic, or exterior, paint will serve your purpose. However, one of the drawbacks with water base paint includes grease and tire contact marking and clinging to the paint at a more visible magnitude. Furthermore, water base paint (especially yellow) may require higher maintenance and more coats of paint for a cleaner finished look. If you are searching for a more durable product an oil-base traffic, or exterior, paint will function well. This paint will be more impervious to oil, grease, and tire marking. Also, oil-base paint will have more weather resistance than a water base product. With either product, just make sure you have a clean surface and complete your proper prep work to ensure paint adhesion. If you can tell me what paints are available to you and by what means you can attain paint I can hopefully direct you to a source. Thanks for your efforts overseas!

    • I’m trying to do some research for a project I’m working on. Question: Are there strict specifications/guidelines for the lines used to delineate cars parallel parked to a curb in Los Angeles County? I know some curb parking places have lines (like a “T”) that mark where cars should be parked – close to the curb, not to close to oncoming traffic. Can you tell me what those measurements are or point to CA codes that tell you what they must be? Many thanks. This will help with my drawings I want to include with my paper. Thanks again.

      Stall dimensions and requirements fall under a city’s municipal code. Typically, a parallel, or t-stall, will consist of an 8′ x 22′ dimension. However, some cities will reflect variations. For example, the cities of Rosemead and Commerce in California require 9’x22′ stalls. Lastly, the design of the stall (i.e. t-stall, box stall, or parallel stall) is determined by the city in which the property resides. Your specific city’s parking stall codes, designs, and dimensions can be found under our “Standards” link found on our home page. These codes are strictly for the cities and counties found in Southern California. If you have any problems locating the code please contact Scott at Trueline Striping, Inc. for further assistance. Thanks!

    • I am looking for estimates for our church parking lot. About 15 to 20 spaces.

      Please contact us at (800) 603-1116 for a price. We can quote you a price with the following information: 1. What city is the project located? 2. Is the project new layout or a re-stripe per existing layout? 3. Does the project require any ADA stalls complimented by signs, posts, and bumpers? Prices vary regionally. If you are outside of California we even may be able to direct you to a local striping company to complete your project. We look forward to hearing from you.

    • Is there a State, Federal, or other agency that specfies the placement of wheel stops? For example, distances from the sides and end of the parking stall?

      Wheelstop, or concrete bumper, placement is one of those “grey” areas in the parking lot industry. Usually, concrete car stop codes and standards will fall under a city’s juristiction. However, many cities do not have a specification or code for wheelstop placement dimensions. Typically, most cities require the wheelstop placement 24″ to 36″ from the face of the curb, or building structure, to the center of the wheelstop. With our experience 24″ may not be enough area to protect a sign and post or a retaining wall from the overhang of a vehicle. We recommend a minimum of 30″ in order to deter damage to posts or structures and to limit the overhang of a vehicle on a pedestrian path of travel or sidewalk. Please contact us with any other questions!

    • I have a small parking lot, about 75 cars. How many Handicapped spaces am I required to have?

      A parking lot consisting of seventy-five stalls will require three ADA, or disabled, parking stalls. Also, one of those handicap stalls will have to be a van accessible stall. Typically, ADA code requires a ratio of one ADA stall to twenty-five standard stalls. After the first 125 stalls the ratio begins to change. These ratios also change depending on the nature of the property (i.e. retail, industrial, and residential). In addition, handicap parking stalls require proper signs and posts at the head of the stalls and at the entrance of the property. There are many other facets of ADA code which property owners and managers should be aware of when preparing for ADA installation, upgrades, and repairs.
