Vehicle Motion Cues: what it is and how to turn it on
Vehicle Motion Cues is Apple's built-in motion sickness feature, added in iOS 18: animated dots at the edges of the iPhone screen that move with the car's real motion, so your eyes and inner ear stop disagreeing while you read. Turn it on under Settings > Accessibility > Motion. On Android, only newer Samsung Galaxy flagships have an equivalent (Samsung calls it Motion Cues); Pixel and stock Android have none built in.

Why dots on a screen help
Reading in a moving car is the textbook trigger for motion sickness: your eyes lock onto a page that isn't moving while your inner ear reports every brake and corner. That disagreement between the two senses is what makes you feel sick. Vehicle Motion Cues resolves part of it by adding a motion signal into the screen — the dots drift opposite to the car's acceleration, so your visual system finally sees something that agrees with what your body feels.
It's the same principle behind the oldest advice in travel: look at the horizon. The horizon gives your eyes a true motion reference; the dots are a miniature version of one you can carry while reading.
How to turn it on (iPhone, iOS 18+)
- Open Settings and tap Accessibility.
- Tap Motion.
- Tap Vehicle Motion Cues.
- Choose Automatic — the dots appear only when the iPhone detects you're riding in a vehicle, and disappear when the motion stops.
You can also add it to Control Center (Settings > Control Center) for a one-tap toggle before a journey. The feature requires iOS 18 or later — on earlier iOS versions the menu item simply isn't there.
The Android situation, phone by phone
| Phone | Built-in feature | Where |
|---|---|---|
| iPhone (iOS 18+) | Vehicle Motion Cues | Settings > Accessibility > Motion |
| Samsung Galaxy S25 series | Motion Cues (Samsung's version) | Settings > Accessibility > Vision enhancements |
| Google Pixel | None built in | Third-party app needed |
| Other Android | None built in | Third-party app needed |
The device-specific walk-throughs live on their own pages: Samsung Motion Cues, Pixel options, and the full Android answer. If you've heard people talk about “the motion sickness dots”, that's this same feature by its street name.
Does it actually work — and where it stops helping
The mechanism is well-grounded: reducing visual-vestibular conflict is the same principle behind every evidence-backed visual fix for motion sickness. Apple built the feature on it, and user reports are largely positive. What doesn't exist yet is an independent published trial of the feature itself — so the honest framing is “free, built in, mechanistically sensible, worth turning on” rather than “proven.”
Its two hard limits: the dots only help while you're looking at the screen, and they are prevention, not rescue — once nausea has already set in, visual cues rarely pull you back. At that point the moves that help are putting the phone down, getting cool air and a forward view, and slow breathing.

Frequently asked questions
What is Vehicle Motion Cues?+
Vehicle Motion Cues is an iPhone accessibility feature Apple added in iOS 18. When you're riding in a car, it shows small animated dots along the edges of the screen that move with the vehicle's actual motion — braking, accelerating, turning. That gives your eyes a motion signal that matches what your inner ear feels, which reduces the sensory conflict that causes motion sickness while reading or scrolling in a moving vehicle.
How do I turn on Vehicle Motion Cues on iPhone?+
Open Settings > Accessibility > Motion > Vehicle Motion Cues and choose Automatic (the dots appear only when your iPhone detects you're in a moving vehicle) or On. You can also add it to Control Center for one-tap access. It requires iOS 18 or later.
Does Android have Vehicle Motion Cues?+
Not under that name, and not on most phones. Stock Android — including Google Pixel — has no built-in equivalent. Newer Samsung Galaxy flagships (the S25 series) have Samsung's own version, called Motion Cues, under Settings > Accessibility > Vision enhancements. On other Android phones, a third-party app such as KineStop overlays similar moving cues, or a sound-based app works without needing you to look at the screen.
Does Samsung have Vehicle Motion Cues?+
Samsung's version is called Motion Cues (without the 'Vehicle'). It ships on the Galaxy S25 series under Settings > Accessibility > Vision enhancements, and Samsung has been expanding it to more models. If the toggle isn't in that menu on your Galaxy, your model or software version doesn't have it yet.
Do Vehicle Motion Cues actually work?+
The mechanism is sound: motion sickness while reading in a car comes from your eyes reporting a stationary page while your inner ear reports movement, and giving the eyes a matching motion signal reduces that conflict. Apple built the feature on that principle, and many users report it helps. Independent published trials of the feature itself haven't appeared yet, so honest advice is: it's free, built in, and worth turning on — and if you're still queasy with it on, the dots only help while you're looking at the screen.
What are the limitations of Vehicle Motion Cues?+
Two main ones. First, it only helps while your eyes are on the screen — it does nothing once you put the phone down, close your eyes, or look out the window. Second, it's prevention rather than rescue: it reduces the conflict that builds nausea, but once you already feel sick, dots on a screen rarely bring you back. For that situation, put the phone away, get a forward view or fresh air, and consider a sound-based option that works with your eyes closed.
