12.1 Transportation and Vehicle Safety
Key Takeaways
- OAC 35:30-17-15 requires every commercial spray vehicle used in the conduct of business — including nurse tanks and self-propelled ground applicators — to display the licensee's name and license number on both sides in letters not less than two (2) inches high.
- 40 CFR 171.103(c)(2)(ix) tests proper identification, storage, transport, handling, mixing, and disposal of pesticides and used containers, including keeping children away from them.
- Secure containers upright in original labeled packaging, tied down and separate from food, feed, and passengers; inspect hoses and tanks before you roll; never leave restricted use pesticides unattended in an open bed in town; and carry a spill kit of absorbent, PPE, shovel, bags, water, and SDS or labels.
- OAC 35:30-17-26(a): every container used to dispense pesticide, except rodent bait boxes, must be accompanied by a readable label for the product inside — attached to the container or present on or in the transporting vehicle.
- OAC 35:30-17-26(b): a rodent bait box in an accessible area that is not locked or secured against tampering must carry an attached readable statement giving the EPA registration number, active ingredient, recognized trade name, signal information, and the application company's name and address.
12.1 Transportation and Vehicle Safety
Quick Answer: Treat every Oklahoma pickup, Category 7A van, nurse tank, and self-propelled rig as a moving pesticide store. Keep original labels, keep containers upright and tied, keep product away from food, feed, and people, and keep a spill kit in the vehicle. OAC 35:30-17-15 puts the licensee's name and license number on both sides of commercial vehicles used in the conduct of business, including nurse tanks and self-propelled ground applicators, in letters not less than two (2) inches high. Do not leave restricted use pesticides (RUPs) unattended in an open bed in town.
Why the load is a Core question
Federal commercial-applicator core standards in 40 CFR 171.103(c)(2)(ix) require practical knowledge of proper identification, storage, transport, handling, mixing procedures, and disposal methods for pesticides and used pesticide containers, including precautions to prevent children from having access. Section 12.2 is the locked shed. This section is the mile between the shed and the job: a Caddo County wheat field, a Stillwater turf account, or a kitchen in Oklahoma City. Most concentrate that ever reaches a storm drain, a cab floor, or a child's hand did not jump there by itself. It rode in a truck.
This OpenExamPrep chapter is independent study material on those transport duties. It is not an Oklahoma Department of Agriculture, Food, and Forestry (ODAFF) publication and does not claim ODAFF review, partnership, or official approval.
Who must stand on the site during the application, including Oklahoma service technician presence rules, belongs in Chapter 13. This section is the cargo, the markings, and the kit — not the supervision roster.
Secure, upright, original labels
Move product in original containers with legible labels. A jug poured into an unmarked soda bottle, a diesel can, or a Gatorade jug is an identification failure under 40 CFR 171.103(c)(2)(ix) before it is a spill. If you must move a leaking container, put it in a salvage drum or overpack, keep the label or a copy with the material, and treat the whole package as a leak in transit — not as ordinary freight.
Oklahoma turns that habit into a rule you can be cited for. OAC 35:30-17-26(a): every container used to dispense (apply) pesticide — the service jug, the backpack, the hand can, the spray rig — shall be accompanied by a copy of a readable label for the pesticide inside it. The label may be attached to the container or be present on or in the vehicle used to transport that container. Rodent-control bait boxes are the only exception to that dispensing-container sentence. This is why a laminated label book, or a label sleeve in the van, is not decoration on a Category 7A route: the technician holding the sprayer must be able to produce the readable label for what is in it, from the container or from the vehicle.
OAC 35:30-17-26(b) then marks the bait box itself. Every rodent-control bait box in an accessible area that is not locked or secured against tampering must have attached to it a readable statement containing five things: the EPA registration number; the active ingredient; the recognized trade name of the pesticide; the appropriate signal information (caution, warning, or danger – poison); and the name and address of the pesticide application company. A station behind a Tulsa restaurant dumpster with a faded sticker and no company address fails that rule even if the bait inside is perfectly legal. A locked or tamper-secured station in that same alley is outside subsection (b) — secure the box or label it.
Upright is not a slogan. Liquid concentrates, emulsifiable concentrates, and flowables leak at the cap and vent when they ride on their sides. Caps back on. Bungs tight. Dry bags and water-dispersible granules off the bed floor if the bed can pond rain. Tiedowns, straps, and a locked box or bulkhead keep a stack from becoming projectiles on I-40 or a two-lane in Harmon County. An open pickup with jugs walking toward the tailgate is not a secure load.
Separate pesticides from food, feed, and passengers. That includes the crew's lunch, a bag of dog food, seed, mineral, and the extra cab seat. A Category 7A restaurant van is the exam picture: cockroach bait, rodent bait, and spray concentrate do not ride in the same tote as the technician's sandwiches or anything that will enter a kitchen. Put chemicals in a lockable, labeled compartment; keep food and clean PPE in another. Agricultural pickups make the same mistake with a box of range cubes sliding against a 2,4-D jug.
The spill kit that actually gets used
A kit you cannot reach from the leak is decoration. Keep it on the vehicle, not back at the shop in Enid while the truck is in Lawton. Minimum useful contents:
| Kit item | Why it is on the truck |
|---|---|
| Absorbent (pads, clay, or labeled spill absorbent) | Stops liquid from reaching soil, pavement, and drains |
| Personal protective equipment (PPE) at least as protective as the label for handling concentrate | You cannot contain a leak with bare hands |
| Shovel and stiff broom | Dry product and spent absorbent have to be lifted, not rinsed |
| Heavy bags or drums | Hold debris as pesticide waste, not as ordinary trash |
| Water for labeled decontamination of skin and equipment when the label allows it | Not for washing product into the gutter |
| Safety data sheets (SDS) and labels (paper or an offline electronic copy) | Spill instructions, first aid, and identity when a jug's paper is soaked |
Water in the kit is for people and tools, not for making a spill "go away." Section 12.3 covers control, contain, clean up. The exam trap is using the wash water as a disposal method on a parking lot.
Oklahoma vehicle identification
OAC 35:30-17-15 is short and testable. All vehicles, including nurse tanks and self-propelled ground applicators, used by a commercial applicator during the conduct of business shall be identified by displaying the name and license number of the licensee. The display shall be on both sides of the vehicle in letters not less than two (2) inches in height.
Chapter 3 introduced that rule as a licensing condition. Here it is an operations condition. A nurse tank towed to a wheat field in the Panhandle is not exempt because it is "just a tank." A self-propelled ground applicator is not exempt because the name is on the pickup that pulled the trailer. Both sides, not the tailgate only. Name and license number, not a cute company slogan without the number. Two inches or larger, not a one-inch vinyl that an inspector cannot read from the ditch. Magnetic signs that fall off on the first washboard road do not meet the duty while they are in the cab.
Inspect hoses, valves, pumps, and tanks before you leave the yard and again after a rough road. A cracked nurse-tank hose that weeps into the borrow ditch is a transport spill, not a "later maintenance" item. Check caps, sight gauges, and the discharge valve lock. If the tank has a home-built plumbing change, treat it as a leak source until you prove it is not.
Weather, tiedowns, and damaged containers
Oklahoma weather is part of the load plan. August metal beds cook emulsifiable concentrates and pressurize containers. January nights freeze water-based products and split jugs. Thunderstorms fill an open bed and float bags into the wheel wells. Shade, a lockable box, a tarp that does not collect ponds, and insulation from the exhaust are transport controls, not comfort. Tie the load so a hard stop on a Norman on-ramp does not throw jugs into traffic.
Never leave RUPs unattended in an open bed in town. 40 CFR 171.103(c)(10)(i) is maintaining chemical security for restricted use pesticides. An unlocked pickup at a convenience store on North Lincoln, at a school parking lot, or in front of the restaurant you are about to treat, with RUP jugs visible, is a security failure and a child-access failure under (c)(2)(ix). If you must stop, the product goes in a locked compartment or you stay with the vehicle. General-use products are not a toy either; they still have labels, still injure children, and still look like sports drinks when the label is gone.
Damaged containers do not ride as ordinary freight. Overpack them. Keep them upright if liquid remains. Do not put a leaking jug on the passenger floor "so you can watch it." Do not stack a crushed bag of granules on seed or fertilizer. If the label is destroyed, you have a waste-identity problem; do not invent a name. Section 12.4's Oklahoma Unwanted Pesticide Disposal Program is how unwanted concentrate leaves the inventory — not the dumpster behind the shop.
DOT placards: the general rule only
U.S. Department of Transportation (DOT) hazardous-materials rules in 49 CFR can require shipping papers, trained drivers, and placards for commercial highway transport of certain materials in certain quantities. Those quantities depend on hazard class, packing group, limited-quantity exceptions, and other current 49 CFR provisions. This guide does not invent a single pound or gallon number as "the Oklahoma pesticide placard threshold." If a test option quotes a homemade 1,000-pound rule, treat it as unverified unless the question cites a current 49 CFR table. Many farm-to-field moves of original labeled packages still require secure, upright transport even when placards are not required. The SDS and the shipper of a bulk load will tell you when a highway shipment is a hazmat load. Secure transport is always required. Placards are additional when 49 CFR says they are.
