What this exam is — and who should take it

Transportation is the PE Civil exam for engineers who design and operate roads: traffic and capacity analysis, highway geometry, intersections and interchanges, signals, signing and work zones, and the roadside. It also reaches below and beside the road. Geotechnical and pavement, drainage and project management carry 20 to 30 of the 80 questions. It's also an exam about finding the right page: alongside the PE Civil Reference Handbook you get nine design standards, opened one chapter at a time. You only pass one Civil exam to get licensed, so sit the one that matches your work.

The second-most-taken PE Civil exam: 5,460 examinees in NCEES's 2024–25 fiscal year. Two of its nine supplied design standards, the Highway Capacity Manual and the MUTCD, move to new editions with the April 2027 exam. NCEES scores against a scaled cut score — there's no published passing percentage. Expect standard multiple choice plus alternative item types. Areas and weights follow the NCEES specification effective April 2024; the design-standards list supplied with the exam changes with the April 2027 exam. Pass rates shown are from the July-2026 NCEES refresh (January–June 2026 population); NCEES refreshes them each July and January.

What's on the exam — and where we put your reps

10 areas. NCEES gives each a question range, not a fixed count, and every form totals 80 (official area titles + ranges per the NCEES specification).

Traffic Engineering

10–15 of 80

Where points go — The largest area: level of service and capacity on freeway, multilane, two-lane highway and urban street facilities, intersection and roundabout capacity, volume and speed studies, peak-hour factor, trip generation, crash rates and Highway Safety Manual crash prediction. The capacity half runs through the Highway Capacity Manual and the safety half through the Highway Safety Manual, so knowing which chapter holds which facility or method is half the work.

Your reps — Capacity, LOS and safety problems on state highways, urban arterials, roundabouts and access roads, with HCM-based problems set on the 7th edition and labelled for the April 2027 window. Ask the tutor which HCM procedure applies and why.

Horizontal Design

8–12 of 80

Where points go — Circular-curve geometry and stationing, chord versus arc definition, sight distance around obstructions on the inside of a curve, superelevation rates and runoff, spirals, and compound and reverse curves.

Your reps — Curve layout and superelevation problems from stakeout notes to runoff on divided highways, plus drag-and-drop items where you place each curve element or superelevation point on the drawing.

Full area guide →

Vertical Design

8–12 of 80

Where points go — Vertical-curve geometry, high and low points, clearance under structures, and the crest lengths that stopping and passing sight distance require, and the sag lengths that headlight sight distance and comfort require.

Your reps — Crest and sag curves drawn as profiles, including clearance at overpasses and headlight sight distance on unlit sags, so you practice reading the profile the exam gives you.

Full area guide →

Drainage

8–12 of 80

Where points go — Rational-method and synthetic-hydrograph runoff, water-quality measures, gutter spread and inlets, culverts in inlet and outlet control, open channels, energy dissipation and detention.

Your reps — Culvert, inlet and gutter-spread problems drawn as profiles and plans, worked with HDS-5 and the Green Book the way the exam supplies them.

Full area guide →

Roadside and Cross-Section Design

7–11 of 80

Where points go — Clear zones and recoverable slopes, barrier selection, deflection, placement and end treatments, lane, shoulder and curb choices, retaining-wall offsets, and sidewalks, bike lanes and shared-use paths.

Your reps — Roadside and cross-section problems set beside culverts, ponds and walls, including select-all items on barrier placement and point-and-click items on the drawing.

Full area guide →

Intersection Geometry

7–11 of 80

Where points go — Intersection sight distance, turn-lane and speed-change-lane lengths, ramp and interchange design, lane balance, and at-grade and roundabout layout.

Your reps — Approach sight triangles, entrance and exit ramps and turn-lane problems drawn as plans, with a tutor you can ask to walk the Green Book table you'd use.

Full area guide →

Project Management

6–9 of 80

Where points go — Quantity take-offs and cost estimates, activity networks, float and the critical path, earned value, and comparing alternatives on present worth and lifecycle cost.

Your reps — Estimating, scheduling and economic-comparison problems set on real road projects (shoulder paving, ramp reconstruction, rail-crossing alternatives), so planning practice stays on the exam's ground.

Full area guide →

Geotechnical and Pavement

6–9 of 80

Where points go — Soil classification and testing, phase relationships and permeability, compaction, earthwork and borrow volumes, asphalt mix properties, subgrade strength (CBR, R-value, resilient modulus), traffic loading, and flexible and rigid pavement design and rehabilitation.

Your reps — Lab-data, earthwork and pavement-design problems, from shrink and swell on borrow to the AASHTO-93 structural number and the mechanistic-empirical guide.

Full area guide →

Traffic Signals

5–8 of 80

Where points go — Yellow change and red clearance intervals, pedestrian timing, cycle length and green splits, signal warrants including the intersection-near-a-grade-crossing warrant, railroad preemption, and signal-head design.

Your reps — Signal-timing and warrant problems from yellow intervals on grades to four-hour volume warrants, with the tutor available to check your interval before you commit.

Full area guide →

Traffic Control Design

5–8 of 80

Where points go — Permanent signs and pavement markings, including sign sizes, advance warning distances, line colors and speed zoning, and temporary traffic control through work zones: tapers, buffers and sign spacing.

Your reps — Signing, marking and work-zone layout problems drawn as plans, where you place, size and space the devices rather than just recall a rule.

How to prepare for this exam

Don't study the areas evenly — weight your time to where the points and the difficulty are.

  1. 1

    Check which design-standards editions your appointment gets you. Until March 2027 the exam supplies the Highway Capacity Manual 6th edition and the 2009 MUTCD (with Revisions 1 and 2); from April 2027 it's the HCM 7th edition and the MUTCD 11th edition. Answers are scored against the listed editions only.

  2. 2

    Diagnose first. Find your weak areas across all ten before you commit your hours.

  3. 3

    Weight your time to the heavy areas (traffic engineering, horizontal and vertical design, and drainage) without leaving signals and traffic control at zero. They're short areas, and most of their questions turn on finding the right MUTCD section and applying it, which you can rehearse.

  4. 4

    Don't skip pavement, soils, drainage and project management. Together they carry 20 to 30 questions, and they're where traffic specialists have the least day-job cover.

  5. 5

    Learn the map, not just the methods: for each area, know which standard holds it (Green Book, HCM, MUTCD, Roadside Design Guide, HSM, HDS-5, the pedestrian facilities guide or the pavement guides) and which chapter.

  6. 6

    Rehearse lookups the way the exam delivers them, one chapter open at a time.

  7. 7

    For every miss, work out why each wrong option is wrong, not only why the right one is right.

  8. 8

    Finish with full-length exams you haven't seen, timed: the NCEES practice exam once, cold, then a mock, to set your pace across the nine-hour appointment.

Frequently asked

What's on the PE Civil Transportation exam?

Ten knowledge areas across 80 questions: project management, traffic engineering, roadside and cross-section design, horizontal design, vertical design, intersection geometry, traffic signals, traffic control design, geotechnical and pavement, and drainage. NCEES gives each area a question range rather than a fixed count; traffic engineering, at 10 to 15, is the largest.

What references do I get on the exam?

The NCEES PE Civil Reference Handbook plus nine design standards, all on-screen: the AASHTO Green Book, Roadside Design Guide, Highway Safety Manual, pavement design guide, mechanistic-empirical pavement guide and pedestrian facilities guide, FHWA's culvert design manual (HDS-5), the Highway Capacity Manual and the MUTCD. They open one chapter at a time.

What changes in April 2027?

Two editions. The Highway Capacity Manual moves from the 6th edition (2016) to the 7th (2022), and the MUTCD moves from the 2009 edition (with Revisions 1 and 2, 2012) to the 11th (2023). The other seven standards stay the same, and the ten areas and their question ranges are identical in both NCEES documents. Our problems that rely on the April 2027 editions are labelled on the problem, so you know which window each one is written for.

What units does it use?

The specification allows both SI and U.S. customary. In practice, expect U.S. customary (feet, mph, veh/h, cfs), with the occasional SI quantity to convert.

What's the pass rate?

61% for first-time takers and 43% for repeat takers in NCEES's July-2026 figures, which cover January–June 2026. About 6 in 10 first-time takers pass.

How should I use the NCEES practice exam?

As a measurement, not a drill. Take it once, timed and cold, and treat the score as a reading of where you are. Each repeat measures memory of those 80 problems more than readiness for new ones.

Transportation or Water Resources & Environmental?

Sit the one that matches your work; you only need one Civil exam to be licensed. The two share ground in drainage, earthwork, soils and project management, and WRE touches basic curve geometry, but Transportation's core is traffic, geometry and the roadside, run through nine design standards. CastorPrep covers both.

Can I use CastorPrep alongside a review course?

Yes. A course teaches the material; CastorPrep is where you practice it on exam-real problems and get unstuck with the tutor.
