These are real pages from the book. The table of contents is the full one: 8 parts and 60 topics.
You're looking at the phase diagram on the plan sheet, and the senior tech asks which phases can run with phase 2. You know the answer is somewhere in that chapter on rings and barriers.
It doesn't come. The manual covers the barrier in half a page of paragraphs: concurrency groups, compatible movements, ring sequences. Sentence after sentence, and not one picture of what's actually moving through the intersection.
In the book, the barrier is one page. A thick line down the middle of the dual-ring diagram: 1, 2, 5, 6 on the left, 3, 4, 7, 8 on the right. One phase per ring, same side of the line: those run together.
The same goes for the open cabinet, load switches, the yellow change formula, loop splices and the 5-step troubleshooting order. Each one has its own page.
You look at the drawing and it makes sense. Next time the plan is spread on the tailgate, you read it without going back to the manual.
The intersection as one map, electricity and safety, the controller cabinet, phases and rings, signal timing, detection, troubleshooting in 5 steps and your exam review: 64 pages, all illustrated.
Think of it this way:
You're on call, the intersection on Main is in flash, and the monitor log is blinking at you. You need to know what each part of that cabinet does, right now.
In the book you open the cabinet page and see it drawn open: 10 numbered parts, from the controller and the MMU to the load bay, the flasher and the relays. Every part in its place, with one line on what it does.
Same with the barrier, yellow worked step by step, pedestrian timing, loop testing and the 5-step troubleshooting order: each one on its own page.
Traffic Signal Tech Illustrated is 8 parts and 60 topics, all drawn, and it ends with the numbers on one page, a cabinet visit checklist and your review plan.
What you see drawn, you don't have to memorize.
The whole intersection on one drawing, mast arm vs. span wire, signal head anatomy, faces per approach, left-turn and ped displays, conduit and pull boxes.
Ohm's Law with a signal example, the 120/240 V service, using the multimeter, grounding and bonding, AC and DC in the cabinet, street and electrical safety.
You open any cabinet and know what each part does: TS 1, TS 2, 332 and ATC, the power panel, the controller, load switches, flash transfer, the MMU, the program card and field terminals.
What a phase is, NEMA 8-phase numbering, the dual-ring diagram, the barrier, lead and lag lefts, overlaps and reading the phase diagram on the plan.
The intervals in order, pretimed vs. actuated, the yellow change formula worked step by step, all-red, pedestrian timing, cycle-split-offset and preemption.
How a loop works, loop layouts, sawcut and install, lead-in and splice, amplifier settings, testing a loop, video, radar and microwave, and accessible ped signals.
You arrive at every fault with the same order: the 5 steps, a dark or flashing intersection, reading the monitor before reset, and each fault drawn: dark, flash, stuck phase, one indication out, detector.
The numbers on one page, terms that get mixed up, signal indications, common shop mistakes, the cabinet visit checklist and your review plan.
At the end of the book: The numbers on one page, a cabinet visit checklist and a review plan to exam day.
Practice every topic of the Level I outline with exam-style questions, and see in one line why each answer is right or wrong.
Review the errors new techs make most often, from loop splices to flash transfer, each one drawn wrong and right on the same card.

Yes. It starts from the whole intersection and builds up to timing and troubleshooting. If you already do electrical work, Part II is a quick review and the rest is signal-specific: phases, rings, timing, detection.
It's checked against the MUTCD 11th Edition (FHWA), NFPA 70 National Electrical Code, ITE practice for change and clearance intervals, and the topics in the IMSA Traffic Signal Level I study material. Some states use their own MUTCD or a state supplement (California and Texas, for example), and agencies adopt different NEC editions: always confirm local values with your agency.
No. It's an independent study book, not published, affiliated with or endorsed by IMSA, NFPA or FHWA. It doesn't give you a certificate or count as course hours: your IMSA certification comes from IMSA when you pass their exam. The book is for studying and reviewing before that.
No. It helps you study and review. It doesn't replace IMSA training, your agency's procedures or supervised field work.
No. They're written for this book, following the exam topics, and they aren't official questions from any exam.
As a PDF by email, sent to the address you enter at checkout. The 2 bonus books come the same way.
No. It's a one-time payment.
It comes as a PDF by email, not as a printed book. The PDF is printable: print the whole book or just the pages you need, like the 5-step order and the cabinet checklist, and keep them in the truck.
