What Is the DCAS Traffic Device Maintainer Exam?
The DCAS Traffic Device Maintainer Exam is a computer-based, multiple-choice, NYC public-sector examination that covers the different subjects and skills that are necessary to be a Traffic Device Maintainer. You need to achieve a score of at least 70% to pass. The test is administered by the City Department of Citywide Administrative Services, the same agency that is responsible for hiring special officers, city carpenters, caseworkers, sanitation workers, and more.
Officially, the test is dubbed 'Exam No. 3063'. You can find more information about it in the Notice Examination, which can be viewed on the city website or your OASYS account. The front page of the notice looks like this:
Step #1 - Education and Experience Exam
The Education and Experience Exam is held separately from the DCAS Traffic Device Maintainer exam (usually several weeks prior). The Education and Experience Exam is not so much of an ‘exam’, despite its name, but actually a questionnaire about your education and work experience that you need to fill out online.
It is important to answer truthfully, because if it is revealed that you misrepresented your professional past in some way this may cause your application to be rejected.
Step #2 – Multiple-Choice Test
This is where you really have to show your worth! This part of the recruitment process is aimed at ascertaining whether or not you possess the skills and knowledge required to thrive as a traffic device maintainer. All questions on the test are related in one way or another to the everyday tasks met and handled by New York traffic device maintainers. They might include measurements and unit conversions that are required for the job, procedures that regulate workplace safety, physical principles that guide the use of tools, and more.
The test covers four areas of capability. Let's go over them:
Deductive Reasoning
Deductive Reasoning is the ability to apply general principles to resolve a specific problem. A Traffic Device Maintainer may need to use this skill when applying his work instructions and procedures to a specific work task.

Deductive Reasoning Sample Question:
Five bears – Jinan, Knot, Lee, Mushu, and Nee-Hau – are kept in three adjacent rooms numbered 1-3 from left to right.
• There is at least one bear in each room.
• The knot is in a room to the left of Lee's.
• Mushu and Nee-Hau are not kept in the same room.
• Either Mushu or Jinan, but not both, are kept in room 2.
• Nee-Hau is kept in room 3.
A sixth bear, Osami, is brought into either room 2 or 3. If there are now two bears in each room, which one of the following must be true?
Written Comprehension
A Traffic Device Maintainer must be able to understand written materials used in the workplace. For this reason, the Traffic Device Maintainer exam includes a ‘Written comprehension’ section. (The DCAS refers to this as a ‘written comprehension’ skill but it is more often just referred to as ‘reading comprehension’).

Written Comprehension Sample Question
Hawkins was puzzled. Quasars are powered by matter that shines fiercely as it swirls into a supermassive black hole typically billions of times the mass of the sun. Their light does vary, for example as stars are ripped apart by the black hole's enormous gravity. But these flare-ups make quasars brighten and fade within a few days, not years and decades as Hawkins found.
What happens to a quasar when it enters a black hole?
Memory
As a Traffic Device Maintainer, you must have good memory skills. You will use them when remembering work instructions or directions to a work site. For this reason, the exam includes a memorization section, in which you will be tested on your ability to remember images, words, numbers, or procedures.

Memorization Sample Question
Number Facility
Number Facility is just a term for your ability to handle arithmetical actions – addition, subtraction, multiplication, and division.

If one of the answer choices must be true, we should deduce it based on the information we already have. The first thing to notice is that we know the exact position of N – room 3. The other conditions provide us with some information, but not enough to place any of the other bears in a specific room. Therefore we should look at what we know about the new bear: O can be either in room 2 or 3. Let's check both options:
If O is in room 2:
The second bear in that room can be either M or J since one has to be in room 2 (fourth condition). Now that room 2 is full; we can turn to the other two. According to the second condition, K is left to L. Since neither is in room 2, K is in room 1, and L is in room 3 (together with N). M/J takes the remaining spot in room 1:
| 1 | 2 | 3 |
|
K J/M |
O M/J |
L N |
If O is in room 3:
Room 3 is now full. For K to be to the left of L (second condition), L must be in room 2, and K – in room 1. M and J are placed the same as before.
| 1 | 2 | 3 |
|
K J/M |
L M/J |
O N |
In both cases, K is in room 1, as is stated in answer choice A.
According to the passage, "Quasars are powered by matter that shines fiercely as it swirls into a supermassive black hole".
The man on the left-hand side and the teenager in the center of the image are both wearing hats.
They are the only people wearing hats, so the answer is 2.
The decimal point can move an equal amount of places on each side of the quotient
4186 /0.001
= 41860 /0.01
= 418600 /0.1
= 4186000 /1
= 4186000
